Farewell Email to Vendors: 5 Templates for Your Last Week

Here's the short answer. A good farewell email to vendors and external partners is short, specific, and sent 5 to 7 business days before your last day. It thanks them briefly, hands off cleanly to a named replacement, and gives one clear way to stay in touch. Skip company gossip, over-explaining why you're leaving, and vague sign-offs like "let's connect sometime."

The internal goodbye email is the one everyone thinks about. The external one is the one people forget until the day before they leave, when they suddenly remember three account managers, a design agency, a legal contact, and a freelancer who has been quietly making them look good for two years.

That last-minute rush is when most vendor farewells go wrong. The email gets written in six minutes between meetings. Nobody gets introduced to your replacement. Half the addresses come from memory and miss the people who mattered most. Then the reader gets your out-of-office two days later and realizes they don't know who to call.

The rest of this post is the tight version of what to send, who to send it to, and when. Five templates you can steal, plus a small list of things not to say.

Who counts as a "vendor or external partner" here

Broader than you think. Not just the SaaS renewals in your name. Also: the recruiter who has been sending you candidates, the outside counsel you email once a month, the freelance designer or writer, the printer, the co-marketing contact at a partner company, the analyst who covers your space, the consultant on retainer, the events team at your conference venues, and anyone whose Zoom room you have been in more than three or four times in the last quarter.

If you cannot picture their face but you know their name, they still deserve an email. That is exactly the group most people cut, and it is the group that remembers.

Timing: send 5 to 7 business days before your last day

Earlier than the internal goodbye. External partners need lead time to update their contact, redirect an in-flight deliverable, or say goodbye back. If you send it on your last afternoon, half of them will not see it until you are gone, and any handoff you promised will land on your replacement without warning.

A related note on when to start saying goodbye at work: internally the answer is usually "later than you think." Externally it flips. External partners need earlier warning, because their calendars are not yours to move.

Template 1 — Standard handoff to a named replacement

Use this for the majority of your external contacts. It is the workhorse.

Subject: Handoff: [Your Name] leaving [Company] on [date]

Hi [First name],

Quick note that my last day at [Company] will be [date]. It has been really good working with you these past [rough duration].

Going forward, [Replacement's Name] ([replacement email]) will be your main contact on our side. I've briefed them on where we are with [the current project or account], and I'll do a proper handoff call with them this week so nothing slips.

If you have anything urgent before [date], reply to this and I'll make sure it lands with the right person. Otherwise, thank you for the last [duration] — you made this part of the job easier than it had any right to be.

Best,
[Your name]

Template 2 — Handoff when there is no named replacement yet

Common. Do not pretend there is one.

Subject: Update on our work together — [Your Name] leaving [Company]

Hi [First name],

Heads up: my last day at [Company] is [date]. My role hasn't been backfilled yet, so in the interim [Manager's Name] ([manager email]) will be the point of contact for [account or project]. I've flagged our current status with them so you won't need to catch anyone up from scratch.

Two open items I want to make sure don't drop:

1. [Specific in-flight item + owner]
2. [Specific in-flight item + owner]

Thanks for the work we've done together — genuinely. I'll be at [new personal contact] if you ever want to say hi.

Best,
[Your name]

Template 3 — Long-standing partner (2+ years)

For the outside counsel of five years, the agency you've renewed three times, the account manager who knows your product roadmap almost as well as you do. Slightly warmer, still short.

Subject: Some news, and a proper thank-you

Hi [First name],

My last day at [Company] is [date]. Wanted you to hear it from me before the transition email.

[Replacement's Name] will pick up our account and I'll walk them through the last year's context, but I couldn't leave without saying this: working with you across [specific project or era, e.g. "the 2024 rebrand" or "the last three renewals"] was one of the parts of this role I'll actually miss. You made complicated things feel manageable, and that is rarer than it should be.

I'll be at [personal email or LinkedIn URL]. Please stay in touch.

Warmly,
[Your name]

Template 4 — Vendors on paused or upcoming renewals

The awkward one. You are leaving, and there is a decision they were hoping you would make. Do not leave it in a state where they wonder if the deal is dead.

Subject: [Company] renewal + my last day

Hi [First name],

Two things worth flagging before I leave [Company] on [date]:

1. The [contract or renewal name] decision is not off the table. [Replacement's Name / Manager's Name] is aware of the timeline and where we landed in our last conversation.
2. They'll want a fresh conversation in [rough month], not a rushed sign-off. I've asked them to reach out directly.

Thanks for being straightforward with us this year — appreciated.

Best,
[Your name]

Template 5 — The individual freelancer or contractor you actually liked

Different in tone. Freelancers work relationship to relationship. They'll want to know where you're going next, because they might follow you there. Send this one from your personal email so they still have you when the work address goes dark.

Subject: Wrapping up at [Company] — and staying in touch

Hi [First name],

My last day at [Company] is [date]. Wanted to reach out from my personal address so you actually have me after I'm gone.

Working with you on [specific project(s)] made a real difference — the [specific quality of their work, e.g. "quick turnarounds on the launch assets"] was noticed by a lot of people internally, even the ones who never said so.

I'm heading to [new role, one line, no drama]. If our paths cross professionally, I'll be very glad. I'll be at [personal email + LinkedIn URL].

Take care,
[Your name]

The part everyone forgets: who exactly do you send this to?

You will write the templates in half an hour. The recipient list is where the whole thing lives or dies. This is the moment where most external farewells go 60% correct — you'll catch the obvious contacts and miss the ones you only met with monthly, who then hear about your departure from someone else and feel it as a small slight.

The most reliable list is not in your head, and it is not in your CRM. It is in your calendar. Every recurring external meeting from the last 90 days is a person who mattered enough to schedule around. Every one-off external call is a person you at least chose to speak with. That is the recipient list, pared down to the ones you'd genuinely want to keep in your professional world.

Five things to leave out of a vendor farewell

1. Why you're leaving. External partners do not need the story. A single sentence about where you're going next is plenty, and only in the warmer templates.
2. Blanket "let's stay in touch" with no address. If you mean it, give them a personal email or a LinkedIn URL. Otherwise skip it. This is the same pattern that turns internal farewells hollow — worth a look at the 6 farewell email mistakes people make on their last day.
3. Grievances. Even the vendor who missed two deadlines. Especially them. Whatever satisfaction the sentence gives you fades in a day; the reputation of the sentence outlives you.
4. Detail your replacement should own. Do not paste account context into the goodbye email — that belongs in a proper warm handoff email from your replacement, sent after yours. Two emails, two purposes.
5. An apology for leaving. You are moving jobs. It is not an insult to them.

One send, two lists

The simplest way to do this: split your external recipients into two groups. Group A gets an individually addressed email (Templates 1, 3, 4, and 5) — anyone you have real relationship equity with. Group B gets Template 2 as a small BCC batch — anyone you know professionally but not personally.

Send Group A first, over two days if the list is long. Send Group B last, so if anyone from Group B replies "wait, who is my new contact?" you can answer without it disrupting your last real conversations.

What to do the day after you send

Reply to any responses within 24 hours. This is where the "warm" in warm handoff actually happens — a two-line reply that introduces the replacement by name and copies them in is worth ten LinkedIn connection requests.

Then move on. You are not obligated to stay involved in their transition after your last day, and it is better for your replacement if you don't. The relationships that are meant to survive will survive, and the tool at itwasgreatworkingwithyou.com is designed exactly for the moment of building that "who to keep" list so you don't lose the ones that matter.

The best vendor farewells feel unhurried. Not long — unhurried. That is the whole difference.
