The defendant, Carl Evans d/b/a Warehouse Club Distributing Company (Evans), appeals an order of the Superior Court (McHugh, J.) denying his motions to vacate judgment and to dismiss. We reverse.
The following facts are contained in the record. The plaintiff, Impact Food Sales, Inc. (Impact Food), located in Salem, is in the business of buying wholesale lots of food products. On November 26,2007, its attorney executed a writ of summons alleging that Evans accepted money from Impact Food for the purchase of goods that were not delivered. Evans is a resident of the State of Illinois.
On November 26, Impact Food’s attorney sent a letter to the Merrimack County Sheriff enclosing a copy of the writ of summons, along with copies for service on the New Hampshire Secretary of State and a check for $10.00, pursuant to RSA 510:4 (1997). That day, Impact Food also sent a copy of the same letter by certified mail to Evans. The secretary of state was served on November 29, and the writ of summons and the affidavit of service from the sheriff were filed with the superior court on December 10.
On January 31, 2008, Impact Food filed a motion for entry of default, alleging that service on Evans had been completed “by having a copy of the writ served upon the NH Secretary of State and consistent with RSA 510:4 plaintiff mailed a copy of the writ to the defendant certified mail, return receipt requested.” The motion further stated that:
4. Defendant appears to have been duly notified by the US Postal Service on at least two occasions and did not arrange to pick up copies of the certified mail.
*3895. In an effort to insure that the defendant was made fully aware of this law suit against him, counsel for plaintiff again mailed a copy of the writ of summons certified mail, return receipt requested.
6. Plaintiffs counsel has not yet received any response from the US Postal Service, however, attached hereto is plaintiffs counsel file copy of a letter mailed first class mail to the same address for the defendant as the certified mail on January 15, 2008 advising the defendant of the process that had been served upon the Secretary of State against him ....
7. This mail sent first class mail has not been returned by the US Postal Service despite counsel’s use of a clearly addressed envelope with a clearly marked return address.
In an affidavit of mailing attached to the motion, Impact Food’s attorney attested that he “served the Secretary of State in accordance with RSA 510:4 and immediately mailed a copy of the process with a copy of the attached cover letter certified mail..., however, the green post card return receipt requested was never received back from the postal service.” The attached cover letter referenced in the affidavit states, “Enclosed please find Writ of Summons along with copies for service on the ... Secretary of State.”
On February 7, the trial court granted Impact Food’s motion and a default judgment was entered against Evans on May 6. On March 20,2009, Evans filed a motion to vacate judgment and motion to dismiss, stating that he was never served in accordance with the statutory requirements set forth in RSA 510:4 and thus the court lacked personal jurisdiction over him. In an affidavit attached to the motion, he attested that he “was never served with the Writ of Summons in this matter . . . [and] never signed a green card for any certified mail alleged to have been sent to Carl Evans doing business as Warehouse Club Distributing Company.” He further attested that he “was notified of a judgment entered against [him] in New Hampshire when [he] received a Citation to Discover Assets in the Circuit Court for the Nineteenth Judicial Circuit — Lake County, Illinois that was issued on December 4,2008.” On April 23, the trial court denied the motion, ruling that “[a]dequate service has been made in this essentially theft of money by the defendant case.” This appeal followed.
On appeal, Evans argues that the trial court improperly found that he was served in accordance with RSA 510:4 and erred in denying his motion to vacate judgment and motion to dismiss. He argues that Impact Food failed to follow the requirements of the statute and instead “attempted to *390create its own service of process contrary to both New Hampshire Statute and existing case law.” Impact Food responds that RSA 510:4 only requires that certified mail be sent to the defendant and that additional service is optional. Based upon case law from other states, Impact Food argues that when certified mail is unclaimed, notice by regular mail is adequate.
RSA 510:4 is this state’s long-arm statute. South Down Recreation Assoc. v. Moran, 141 N.H. 484, 486 (1996). In order to obtain jurisdiction over an out-of-state defendant, proper service of process is required. Id. “Proper service is separate from the due process requirement that the defendant have minimum contacts with the jurisdiction.” Estate of Lunt v. Gaylor, 150 N.H. 96, 97 (2003) (quotation omitted). The interpretation of a statute is a question of law, which we review de novo. Carlisle v. Frisbie Mem. Hosp., 152 N.H. 762, 773 (2005).
Pursuant to RSA 510:4, I, “Any person who is not an inhabitant of this state and who . . . transacts any business within this state, commits a tortious act within this state, or has the ownership, use, or possession of any real or personal property situated in this state submits himself... to the jurisdiction of the courts of this state____” The method of service of process on persons subject to the jurisdiction of this state is set forth in RSA 510:4, II. The statute provides:
SERVICE OF PROCESS ON SECRETARY OF STATE. Service of process upon any person who is subject to the jurisdiction of this state, as provided in this section, may be made by leaving a copy thereof, with a fee of $10, in the hands or office of the secretary of state. Such service shall be of the same legal force and effect as if served on the defendant at his abode or place of business in the state or country where he resides and according to the law of that state or country, provided that notice thereof and a copy of the process is forthwith sent by registered mail, postage prepaid, by the plaintiff or his attorney to the defendant at his last known abode or place of business in the state or country in which the defendant resides. The defendant’s return receipt and an affidavit of the plaintiff or his attorney of compliance with the section shall be appended to the process and entered therewith. In the event that the notice and a copy of the process are not delivered to or accepted by the defendant, the court may order such additional notice, if any, as justice may require.
We note that according to RSA 21:32-a (2000), the words “registered mail” when used in connection with the requirement for notice by mail “shall mean either registered mail or certified mail.”
*391When construing a statute, we first examine the language found in the statute and where possible, we ascribe the plain and ordinary meaning to words used. Collden Corp. v. Town of Wolfeboro, 159 N.H. 747, 750 (2010). When a statute’s language is plain and unambiguous, we need not look beyond it for further indicators of legislative intent. Id. Courts can neither ignore the plain language of the legislation nor add words which the lawmakers did not see fit to include. Id. We require “strict compliance with statutory requirements for service of process.” South Down, 141 N.H. at 487; see Lachapelle v. Town of Goffstown, 134 N.H. 478, 479-80 (1991). ‘Where a statute points out a particular method of serving process ... such method must be followed...” Bissonnette v. Alpine, Inc., 96 N.H. 419, 420 (1951).
Pursuant to RSA 510:4, II, in order to effect valid service of process over a nonresident defendant, several steps must be taken. First, “[s]ervice of process ... may be made by leaving a copy thereof, with a fee of $10, in the hands or office of the secretary of state.” RSA 510:4, II. Second, the plaintiff must send a “notice thereof and a copy of the process” by registered mail, postage prepaid, to the defendant at his last known abode or place of business in the state or country in which the defendant resides. Id. Third, “[t]he defendant’s return receipt and an affidavit of the plaintiff or his attorney of compliance with [RSA 510:4, II]” must be attached to the process and filed with the trial court. Id. If a copy of the process is not delivered to or accepted by the defendant, the court may order additional notice. Id.
Impact Food did not follow this statutory procedure. Initially we note that although the record is not clear, it appears that Impact Food sent a letter to the sheriff’s office enclosing a writ of summons, along with copies for service on the secretary of state and simultaneously sent a copy of the same letter by certified mail to Evans. The statute, however, requires that the certified mailing to the defendant include notice of the effected service on the secretary of state, which it could not have done if the mailing to the defendant was accomplished simultaneously with that to the sheriff’s office. This same issue was addressed by the United States Court of Appeals for the First Circuit in M & K Welding, Inc. v. Leasing Partners, LLC, 386 F.3d 361 (1st Cir. 2004).
In M & K Welding, to comply with the service of process requirements under RSA 510:4, II, the plaintiff sent copies of a summons and complaint to the Merrimack County Sheriff for service on the secretary of state. On the same day, the plaintiff sent another copy of the documents by registered mail to the defendant’s address in New Jersey. Id. at 363. In the letter to the defendant, the plaintiff stated that it had on that day “forwarded copies of the Writ of Summons and Complaint to the *392Merrimack County Sheriff for service upon the New Hampshire Secretary of State, as required by statute.” Id. (quotation omitted). The deputy sheriff’s return indicated that service on the secretary of state was made on September 12,2002. Id. At the defendant’s office, the return receipt for the registered mail had been signed on September 5. Id.
The First Circuit initially reviewed the statutory language, stating that:
[T]he statute proclaims the effect of “service,” defined as leaving a copy plus fee of $10 in the office of the Secretary, as having the same effect as if “served on the defendant at his abode.” This is immediately followed by the proviso, “provided that notice thereof... is forthwith sent... to the defendant.” This can mean only notice of the referent of “thereof,” which is “service” — not intention to make service, expectation that service will take place, or commencement of action hopefully leading to service. Here, notice was given of a preliminary step to service on the Secretary, i.e., sending the documents to a county sheriff for eventual service. . . .
Moreover, “forthwith,” without any definite starting point, loses all significance. In the case at bar, the time referenced could have varied widely. As it happened, [plaintiff] maintains that it meant that a copy of the process was properly sent immediately after its letter requesting service was sent to a sheriff on September 5. But if actual service had been the triggering event, “forthwith” would mean that a copy of the process would have been sent at least a week later.
Id. at 366 (ellipses omitted). Expressing its opinion that it was likely “a New Hampshire court would take literally the requirement in section 510:4, II that notice be given of the actual service on the Secretary of State,” the court declined to stretch the meaning of “notice thereof’ to include notice of actions and stages short of completed service. Id. at 365-66.
We agree with the First Circuit’s construction of RSA 510:4, II. Black’s Law Dictionary defines “service” as: “The formal delivery of a writ, summons, or other legal process . . . [a]lso termed service of process.” Black’S Law Dictionaky 1491 (9th ed. 2009) (italics omitted). Accordingly, service of process does not occur until the process is “in the hands or office of the secretary of state.” RSA 510:4, II. Pursuant to RSA 510:4, III, the secretary of state shall keep a record of all process served, “and said record shall show the date and hour of service in the hands or office of the secretary of state.” (Emphasis added.) Under the plain language of the statute, therefore, notice of service of process on the secretary of state may *393not be given before the service has taken place. To hold otherwise adds words to the statute that the legislature did not see fit to include. See State Employees Assoc. of N.H. v. N.H. Din of Personnel, 158 N.H. 338, 343 (2009) (we will not add language that the legislature did not see fit to include).
In the case before us, Impact Food sent a letter on November 26 to the Merrimack County Sheriff enclosing a copy of the writ of summons, along with copies for service on the secretary of state. That same day, a copy of the letter was sent by certified mail to Evans. The secretary of state was not served, however, until November 29, and the writ and the affidavit of service from the sheriff were not filed with the court until December 10. In order to comply with the statute, Impact Food should have waited to give notice to Evans until after it had effected service on the secretary of state. Short of that, the mailing to Evans on November 26 only contained notice of “the commencement of, or some preliminary stage of, the process of serving.” M & K Welding, 386 F.3d at 366.
Impact Food argues that Evans never raised this issue before the trial court and therefore ought to be precluded from raising it for the first time on appeal. We disagree and read Evans’ arguments made in his motion to vacate judgment and motion to dismiss, and supporting memorandum of law, as adequately raising this issue. See Plourde Sand & Gravel n JGI Eastern, 154 N.H. 791, 799 (2007).
Impact Food also argues that it in fact complied with the requirement that it first serve the secretary of state because on January 15, 2008, it sent a second letter to Evans by certified mail enclosing a copy of the writ and notifying Evans that “the NH Secretary of State has been served as your registered agent in the state for transacting business within this state.” However, assuming, without deciding, that the statement in the January 15 letter that the secretary of state had been served is sufficient to comply with the statutory requirement that notice be given of the effected service on the secretary of state, such service was likewise deficient. RSA 510:4, II requires that notice of service on the secretary of state and a copy of the process be sent “forthwith” to the defendant. Webster’s Dictionary defines “forthwith” as “with dispatch: without delay: within a reasonable time ...: IMMEDIATELY... immediately after some preceding event.” WEBSTER’S Third New International Dictionary 895 (unabridged ed. 2002). Accordingly, the term “forthwith” connotes a sense of immediacy. Here, service on the secretary of state was effected on November 29, 2007. In order for notice thereof and a copy of the process to be sent “forthwith,” such mailing should have occurred immediately after the effected service *394on the secretary of state. We cannot conclude that the second letter mailed to Evans approximately six weeks later satisfies the statutory requirement that notice be sent “forthwith.”
Finally, Impact Food argues that service was effected by sending the copies it had sent by certified mail to the same address via first class mail. RSA 510:4 does not authorize service on an out-of-state defendant by providing notice by first class mail. However, RSA 510:4, II provides, “In the event that the notice and a copy of the process are not delivered to or accepted by the defendant, the court may order such additional notice, if any, as justice may require.” (Emphasis added.) We do not interpret this plain language as authorizing the plaintiff to attempt to effect service of process in a manner not specified by the statute without a court order. See South Down, 141 N.H. at 489 (“[t]he manner of service of process prescribed by the legislature in cases where jurisdiction is acquired under RSA 510:4,1, is via RSA 510:4, II. If that method fails, then plaintiffs may request the superior court to order such additional notice as the case requires, either by virtue of the last sentence of RSA 510:4, II or RSA 510:8”). Rather, under RSA 510:4, II, the legislature has specifically provided that when the notice and a copy of the process are undeliverable or not accepted, a court order is the sole authority for effecting service of process by a method other than that set forth in the statute.
The plaintiff cites case law from other jurisdictions which holds that when certified mail is returned unclaimed and there is evidence that regular mail was received at the same address, then the defendant is deemed to be avoiding service and service by regular mail is adequate. See, e.g., McFarland v. Dippel, 756 So. 2d 618 (La. Ct. App.), cert. denied, 770 So. 2d 349 (La. 2000); First Resolution Inn n Selcer, 795 A.2d 868 (N.J. 2002). The cases cited, however, are governed by the specific language of the applicable statutes or rules. In McFarland, “[u]nder the clear wording of [the long-arm statute], all that is necessary to constitute service upon a non-resident... is that counsel for the plaintiff send a certified copy of the citation and of the petition in the suit to the defendant by registered or certified mail, or actually deliver it in person. There is no requirement under [the statute] for a signed return receipt.” McFarland, 756 So. 2d at 622. Likewise, in First Resolution, a court rule governing service of a notification for wage execution mandated that service “shall be made by registered or certified mail, return receipt requested, to the party’s last known address; or if the party refuses to claim or to accept delivery, by ordinary mail to the last known address.” First Resolution, 795 A.2d at 871 (quotation, ellipsis, and italics omitted).
*395Service is effected only if the provisions of the applicable statute are complied with literally. For example, in Adams v. Sullivan, 110 N.H. 101 (1970), the brother-in-law of the defendant accommodated a deputy sheriff by leaving a copy of a summons and complaint at the defendant’s home on the sheriff’s behalf. Id. at 102. The applicable statute, RSA 510:2, provided that process “shall be served by giving to the defendant or leaving at his abode an attested copy thereof.” Id. at 103 (quotation omitted). Because “writs are addressed to the sheriff in contemplation that he will serve them,” we affirmed dismissal of the suit on the ground that, though actual notice was received, service was not executed by a sheriff. Id. at 103-04. In South Down Recreation, 141 N.H. at 485, out-of-state defendants were served in their home community by a sheriff of that state. We held that RSA 510:4, II does not authorize out-of-state personal service and that the only alternative method recognized is a request to the trial court to order additional service. Id. at 487,489. Finally, most recently, in hunt, 150 N.H. at 97, although service on the secretary of state had been made and, according to counsel, registered mail had been sent to the defendants, we reversed the trial court’s denial of a defendant’s motion to dismiss the suit for lack of personal jurisdiction because there was no record of the registered mail service and return receipts of such service on file with the court as required by RSA 510:4, II.
Citing Nault v. Tirado, 155 N.H. 449 (2007), and Duncan v. McDonough, 105 N.H. 308 (1964), the dissent states that “[t]he ‘overall purpose’ of our statutes governing service of process is to ‘afford[] the defendant constitutionally sufficient notice’ ” and that “the goal of RSA 510:4 must be ‘to provide for notice reasonably calculated, under all the circumstances, to apprise interested parties of the pendency of the action and afford them an opportunity to present their objections.’ ” Nault and Duncan, however, dealt solely with RSA 510:2 and service on in-state defendants. RSA 510:4 was not at issue in either of these two cases and thus they are neither controlling nor persuasive regarding service on an out-of-state defendant.
In Nault, the issue before us was whether pursuant to RSA 510:2, service had been properly perfected on a New Hampshire resident’s “abode.” Nault, 155 N.H. at 451. In Duncan, we concluded that the attempted service on an in-state defendant at the defendant’s liability carrier’s office in Manchester, rather than at his home address in Portsmouth, did not comply with the mandates of RSA 510:2 that “all writs and other processes shall be served by giving to the defendant or leaving at his abode an attested copy thereof...” Duncan, 105 N.H. at 309 (quotation omitted).
“Service of process accomplishes two purposes. First, it establishes the court’s jurisdiction over the defendant or the res in connection with the *396action. Second, it informs the defendant of the pendency and the particulars of the proceeding.... [B]oth must be achieved before any constitutionally sufficient proceedings can begin.” 4 R. WlEBUSCH, New HAMPSHIRE Practice, Civil Practice and Procedure § 14.01, at 300-01 (2d ed. 1997) (emphasis added). Aside from the fact that Nault and Duncan are construing RSA 510:2, which governs resident service, and not RSA 510:4, which governs nonresident service, the dissent’s conclusion that the purpose of our statutes governing service of process is to afford constitutionally sufficient notice undermines the fact that there are two underlying purposes to service of process: providing sufficient notice and establishing the court’s jurisdiction over the defendant. While we agree that notice of the pending action is given by a copy of the writ, jurisdiction over the defendant is established by service. No case can proceed without effected service on the defendant in the manner prescribed by law. Indeed, the fact that a defendant has actual knowledge of attempted service does not render the service effectual if the process was not served in accordance with the requirements of the statute. See Adams, 110 N.H. at 103-04.
Impact Food did not comply with the requirements set forth in RSA 510:4, II for effecting service of process on a nonresident defendant because service on the secretary of state had not occurred prior to Impact Food’s first certified mailing to Evans. “[A] default judgment issued without jurisdiction over a defendant is void, ... it remains vulnerable to being vacated at any time, and ... such jurisdiction depends on the proper service of process. . . .” M & K Welding, 386 F.3d at 364. We hold that because the statutory requirements for service of process were not met in this case, the out-of-state defendant was not properly served and therefore the trial court never obtained personal jurisdiction over him. Accordingly, we reverse the trial court’s order denying Evan’s motion to vacate judgment and motion to dismiss. See Adams, 110 N.H. at 104-05 (RSA 508:10, permitting a new action within one year after judgment, applies to a suit dismissed for defective service of process).
Reversed.
