Resignation email that keeps the door open
Short answer
Three signals do the work: name something specific you're grateful for, name something about the team you'd want to be part of again, and explicitly leave the door open for future conversations. Don't promise to return. Don't say "if things change." Use the phrase "I'd love to stay in touch" once and mean it. Send LinkedIn invites the same week.
You're here because
- You're leaving but want to keep the option to come back
- You don't want to sound like you regret leaving
- You don't want to commit to anything you can't follow through on
- You want the relationship to outlast the role
- You want a written record that's warm without being effusive
The exact email to send
Hi [MANAGER_NAME],
I'm writing to formally resign from my position as [ROLE], effective [LAST_DAY].
This is genuinely a hard decision. The work on [SPECIFIC_PROJECT] and the team itself — particularly [SPECIFIC_PERSON_OR_TEAM_FACT] — are among the best parts of my career so far.
Over the next [TIME], I'll document open projects, train backfills, and close out commitments.
I'd love to stay in touch. If there's ever an opportunity to work together again — same team, different team, or in another capacity — I'd be genuinely open to that conversation. In the meantime, I'll be following [COMPANY]'s progress with interest.
Thank you,
[YOUR_NAME]
- Built for the moment a written offer or deadline lands — not casual browsing.
- Written for the 24–72 hour decision window.
- Designed for people who don't negotiate often.
- Real workplace register — not internet bravado.
What NOT to say
- "If I'd known X, I would've stayed." Don't relitigate the decision.
- Naming a specific timeline for return. "I'll be back in 2 years" reads as performative.
- Generic praise. Specific praise is what builds the door; generic praise sounds rehearsed.
- Mentioning the new company by name. Keep the email about this role, this team.
- Skipping the offer to support the transition. The handoff is part of the door staying open.
An illustrative example
Used the keep-the-door-open email, sent the LinkedIn invite the same week, replied to one team Slack thread three months later. Eighteen months later, when her old company opened a Senior Designer role, her old manager reached out directly. She returned at +22% base over what she'd been making at the startup, with the senior title. The door was the email.
Why this works
Boomerang hires close faster, with less interview load, and at higher seniority than equivalent external candidates. Your old company knows your work — they just need a signal that you're open to being asked. The email does exactly that, in writing, without pressure.
What to do next
Send the email today (or whenever your last-day plan is locked). The Resignation Kit includes the 30-day follow-up note to your old manager, the right cadence for staying in touch without being weird, and the boomerang-return negotiation script if the door opens again.
Before you send — quick check
- Do you have your start date for the next role confirmed in writing?
- Have you decided what to say if asked the reason?
- Have you drafted the email without naming names or grievances?
If you answered "not sure" to any of these, the Resignation Kit walks you through all three.

FAQ
Is this performative? Does anyone actually return?
Boomerang hires are a meaningful share of senior tech hiring (Workday, LinkedIn data routinely cite 4–5% of total). They close faster and often at higher seniority. The door is real.
What if I don't actually want to come back?
Use a different resignation script. The keep-the-door-open wording is for when the option matters to you. The Resignation Kit has neutral and standard variants.
Should I stay in touch with my old manager?
Once a quarter is the right cadence. Comment on their LinkedIn posts, send a short note when they ship something. Don't disappear and reappear only when you need a referral.
