“I’ve heard I should email residency programs to show interest. But should I email every program? What if the program relies on signals? What if it doesn’t want extra communication? What do I say before the interview, and what after? And what exactly is the difference between a letter of interest vs letter of intent for residency?”
Almost every international medical graduate (IMG) asks some version of this each season. The short answer: there is no universal “email every program” rule. Good residency communication is purposeful, truthful, timely and respectful of each program’s communication preferences. The theme of this guide is simple: communicate strategically, not compulsively.
| Key takeaways A letter of interest usually comes before an interview offer; a letter of intent usually comes after interviews. Neither term has a standardized NRMP definition. Use official channels first: ERAS program signals show interest without an email. Anything a program tells you before rank lists close is non-binding, and only your certified rank order list counts. Never tell more than one program they are your #1. When a program or specialty discourages contact, not emailing is the professional choice. |
1. What the formal rules actually say about contacting programs
Formal rule. NRMP rules do not bar applicants and programs from communicating during recruitment, but they set boundaries for both sides. Communication is permitted. It is not mandatory.
Formal rule. The NRMP’s current applicant guidance tells applicants to limit post-interview communication and to seek only the clarifying information they need about the program. The Match Participation Agreement (MPA) you sign at registration also contains interview-conduct policies, in place since the 2023 Main Residency Match. Read the current MPA in R3 yourself; do not rely on summaries, including this one, for exact wording.
Formal rule, in principle. Only your final rank order list counts in the Match. Anything said by either side before rank lists close is non-binding, and a program cannot require you to disclose where you will rank it.
Common practice, specialty norms. Specialty bodies often go further than the NRMP. Specialty-specific guidance generally moves away from thank-you notes and letters of intent, and some specialties, including dermatology, emergency medicine, internal medicine and orthopaedic surgery, strongly discourage post-interview communication. These are recommendations, not NRMP rules, but programs in those specialties may read unsolicited emails less favorably.
Strategy. Your specialty’s norms and each program’s own stated policy outrank any generic template, including every sample email in this guide.
2. Letter of interest vs letter of intent for residency
Neither term has a standardized NRMP definition. Both are common-usage labels, and programs and advisors use them loosely. The working distinction is below.
What is a letter of interest?
- Purpose: to express genuine interest in a specific program and give a concrete reason.
- Typical timing: mostly before an interview offer, while you wait after applying.
- Typical content: a short, specific explanation of fit, such as a track record, a research or clinical match, a geographic tie, or visa-sponsorship alignment.
- When it can help: you have a real connection that is not obvious from your ERAS application (a rotation, observership, research link, family or regional tie), or you have new information since applying.
- When it adds little: a generic “I am very interested in your esteemed program” email gives the program nothing to evaluate and is easy to ignore.
What is a letter of intent?
- Purpose: to tell a program where it stands among your choices, usually after you have interviewed.
- Typical timing: after interviews and before rank lists close.
- Relationship to ranking: it states your intention. It is not a contract, and only the rank list you certify counts.
- How the term is used: loosely. Some applicants use it for any post-interview email of strong interest; others reserve it for an explicit “I plan to rank you first” message.
Update letters and thank-you emails
Common practice. An update letter is a short factual note about something new: a publication, a score, a certification, new clinical experience. It differs from a letter of interest because it gives the program something new to evaluate instead of asking it to feel something.
Etiquette. Thanking people who spent a day with you is courteous. But because specialty guidance often discourages thank-you notes and the NRMP wants post-interview contact limited, keep any thank-you brief, do not pressure or fish for information, and skip it where the program asks for no contact.
Interest is not intent, and intent is not a ranking commitment
| Statement | Meaning | Typical timing | Strength | Important caveat |
| “I am interested in your program” | Genuine interest | Pre- or post-interview | Moderate | Does not imply ranking |
| “Your program is one of my top choices” | Strong interest | Usually post-interview | Strong | Still not a ranking commitment |
| “I expect to rank your program highly” | Ranking preference | Post-interview | Very strong | Must be truthful |
| “I intend to rank your program #1” | Explicit #1 intention | Usually post-interview | Very strong | Only say it if genuinely true |
| “You are my #1 choice” | Explicit first choice | Post-interview | Strongest | Never use casually or for more than one program |
Strategy. The stronger the statement, the more it matters that it is true. Telling two programs they are each your #1 is among the most damaging mistakes in this process, because programs talk to one another and a reputation for dishonesty can outlast a single Match cycle.
3. Pre-interview communication: signals first, email second
Use ERAS program signaling before you write an email
Before emailing anyone, use the formal channel designed for expressing interest. In specialties that participate in program signaling, each specialty gives you a fixed number of signals, and the AAMC advises signaling the programs you are most interested in, including home and away rotation programs. Specialties that use two tiers offer gold signals for “most preferred” programs and silver signals for “preferred” ones.
Allotments differ by specialty and can change between seasons. Published figures have included 3 gold and 12 silver in internal medicine and 3 gold and 25 silver in dermatology. Confirm your specialty’s current numbers on the AAMC website before you plan.
Strategy. If you have already signaled a program, a further “I am interested” email adds little, because the signal already says so. Write only when you have new, specific information a signal cannot carry.
Strategy, geography. Signaling data published for at least one specialty shows that a signal is associated with higher interview rates when it matches your stated geographic preference. This is specialty-specific, so check whether your own specialty shares similar data before generalizing.
When a pre-interview letter of interest is worth sending
- You have a real, checkable connection to the program (rotation, observership, research collaboration, family or regional ties).
- You have achieved something material since submitting your application.
- The program has invited contact, or its website welcomes it.
When not to email before an interview
- The program states that it does not accept unsolicited communication or status inquiries.
- Your message would repeat what your application already says.
- You are emailing mainly because you feel anxious about not hearing back. That is understandable, but it is a reason to wait, not to write.
- You would be sending the same template to many programs.
Etiquette. Do not ask for interview status unless the program’s own process invites it. Repeated status emails can create the opposite impression to the one you want.
Sample pre-interview letter of interest (use only with a genuine connection)
| Subject: Application update and interest in [Program Name], [Specialty] – [Your Name], AAMC ID [XXXXXXXX] Dear Dr. [Program Director’s surname], I applied to your [specialty] program this season and am writing to share one update and one reason for my interest. Since submitting my application, [specific update, e.g., my paper on X was accepted at Y / I completed a four-week observership in Z]. I am particularly drawn to your program because [one concrete, verifiable reason, e.g., your department’s work on ___, which relates to my research on ___]. I understand you receive many applications and will contact applicants according to your own process. Thank you for your time. Sincerely, [Name, medical school, ECFMG ID, contact details] |
Keep it to a few sentences, and do not attach documents unless the program asks for them.
4. Post-interview communication: what the evidence and norms suggest
Formal rule. The logic behind the NRMP’s guidance is that both sides may speak, but programs are not meant to solicit or require post-interview communication, and each side decides on its final list independently.
How programs have reacted: what the data shows
The available data is older and specialty-specific, so treat it as context, not as a rule.
- In a survey of senior students at seven US medical schools about the 2010 Match, 86.4% reported communicating with programs, and 23.4% said they altered their rank list because of those exchanges.
- The same study found that 18.6% felt assured by a program that they would match there, yet did not match despite ranking it first. The lesson for applicants: program statements are non-binding and can mislead even when well meant.
- A 2020 emergency medicine survey summarized in a conference handout reported that 88% of program directors did not believe an applicant’s statement of intent to rank them high, and 75% said such messages did not affect their rank list. This is one specialty and one survey, so do not generalize it to every field.
Strategy. Post-interview emails rarely decide rankings. At most they may matter at the margin, when a program is weighing similar candidates and wants to know you would actually come. Do not send one expecting it to rescue a weak interview.
Five working rules for post-interview messages
- Check the program’s stated policy first. If the program or your specialty discourages post-interview contact, do not send one.
- Be truthful. Say only what you would say if the program later compared notes.
- Do not ask where you stand. Questions like “Where do I rank on your list?” invite the kind of exchange the NRMP guidance discourages.
- Treat program statements as non-binding. “You will be ranked to match” and similar phrases guarantee nothing.
- Keep it short. Three to five sentences is enough.
Sample thank-you email (only if the program does not discourage contact)
| Subject: Thank you – [Your Name], [Specialty] interview on [date] Dear Dr. [Name], Thank you for the opportunity to interview on [date]. I especially valued [one specific moment, e.g., speaking with your residents about the continuity clinic model]. I remain very interested in [Program Name] and appreciate your time. Sincerely, [Name] |
Sample strong-interest message (only if true, and only where the specialty tolerates it)
| Subject: [Your Name] – [Specialty] applicant, interview on [date] Dear Dr. [Name], Following my interview, I wanted to share that [Program Name] is one of my top choices. [One specific reason, e.g., the balance of inpatient training and the program’s record of training IMGs.] Thank you again for your time and consideration. Sincerely, [Name] |
Sample #1 statement (use for one program at most, and only if completely true)
| Subject: [Your Name] – [Specialty] applicant, interview on [date] Dear Dr. [Name], After careful consideration, I intend to rank [Program Name] first. [One genuine reason.] I understand the Match is based on the final lists we each submit. Thank you for the time you have invested in me. Sincerely, [Name] |
Strategy. You can truthfully send this to one program only. It is also the message programs are most skeptical of, so reserve it for a program where you would be genuinely happy to match. In specialties that discourage this kind of message, do not send it.
5. Ranking-related communication and the NRMP Match
- Formal rule. Your final certified rank order list is what the Match algorithm uses. Nothing you or a program says changes that.
- Rank-list lock pilot. The NRMP is continuing its voluntary program rank order list lock pilot for the 2027 Main Residency Match with internal medicine, pediatrics and vascular surgery. It concerns programs’ lists, not a new applicant communication tool, but if you apply in these specialties it is worth checking which programs participate.
- Post-interview visits. Some programs offer them, and the NRMP’s pilot FAQ states that participating in a post-interview visit is voluntary. Attend if it helps you judge fit, not because you fear absence will count against you.
- Etiquette. If a program presses you to reveal your ranking, you do not have to. A courteous reply such as “I am still finalizing my list, but I have enjoyed learning about your program” is honest and sufficient.
6. When not emailing is the more professional choice
Sending nothing is often the right call. Consider staying silent when:
- The program or specialty discourages it. Following stated norms signals good judgment.
- You have nothing new to say. Repeating your application is noise, not communication.
- You are emailing out of anxiety. The urge to “do something” is real, but it is not a strategy.
- You have already signaled. The signal is the message.
- You would have to exaggerate. If you cannot say it truthfully, do not say it.
- You would be sending near-identical emails in bulk. Mass messages are easy to spot and rarely help.
| A test before every email: What new, true information does this give the program, and does this program accept it? If you cannot answer both, do not send it. |
7. Quick reference: should you contact the program?
| Situation | Suggested action | Type of advice |
| Applied, no invitation yet, no new information | Wait; do not email | Strategy |
| Applied, real connection or new achievement | Brief letter of interest or update | Common practice |
| Specialty uses signaling and you have signaled | Do not repeat interest by email | Strategy |
| Just interviewed; program discourages contact | Do not send anything | Etiquette |
| Just interviewed; contact is accepted | Brief thank-you | Etiquette |
| Program is truly your #1 | One truthful, short message, if the specialty tolerates it | Strategy |
| Program presses you to reveal your ranking | Politely decline to specify | Formal rule and etiquette |
8. Frequently asked questions
Is there an NRMP rule that requires a letter of interest or letter of intent?
No. Communication is permitted but not required, and neither term has a standardized NRMP definition. Check the current Match Participation Agreement for the exact conduct rules.
What is the difference between a letter of interest and a letter of intent for residency?
A letter of interest is usually sent before an interview offer to show genuine, specific interest. A letter of intent is usually sent after interviews to state where a program stands among your choices. Both are informal conventions.
Should I email every residency program I applied to?
No. Email only when you have something new, true and relevant to say, and when the program and specialty accept it. Otherwise, rely on your application and any program signals.
If I used a program signal, do I still need a letter of interest?
Usually not. The signal already communicates interest. Write only if you have new information, such as a publication, a score or a new experience.
Can I tell more than one program that it is my #1 choice?
You should not. A #1 statement should be literally true, and you can only have one first choice. Programs also compare impressions, so false assurances can damage your reputation.
Does a thank-you email improve my chances of matching?
The evidence is limited and varies by specialty. A brief, courteous note is acceptable where programs do not discourage contact, but do not expect it to change your ranking.
What if a program says it does not want post-interview communication?
Respect it. Following a program’s stated policy is the professional choice, and ignoring it can reflect poorly on you.
Can a program tell me where I am on its rank list?
Programs sometimes use phrases such as “ranked to match” or “ranked highly,” but these statements are non-binding. Studies show some applicants who felt assured by a program did not match there, so treat such comments with caution.
9. Final word: communicate strategically, not compulsively
Communicating well with programs usually means saying less and saying it truthfully. Read your specialty’s guidance, check each program’s own policy, and send only what is new, honest and welcome. Before you finalize your approach, verify the details on the NRMP, AAMC/ERAS and program websites, because policies and signal allotments can change from one season to the next.
