5 client onboarding email templates you can steal today

Copy these. Adapt them. Use them tomorrow morning. Five messages pulled from the agencies that onboard fastest—covering the moment a client signs, the nudge if they stall, the day before kickoff, the internal prep, and the recovery message when a flow goes quiet.

Send template 1 automatically the moment a contract is signed—no copy-paste required.

Get started

None of these need a subject line longer than the message itself. The goal of each one is the same: remove a decision or a guess the client would otherwise have to make on their own.

Template 1 · Send the moment they sign

The post-signature message

Hi [Name] —

We're officially in. Welcome aboard.

Here's your onboarding link: [link]

Everything we need is in one place — brief, files, contract, payment. Takes about 30 minutes.

The faster you fill it out, the faster we start.

Reply if anything's unclear.

Template 2 · Send 48h after the link, if abandoned

The 48h reminder

Hi [Name] —

Quick nudge — we're holding your kickoff slot for [date].

Still need from you: [auto-pulled list]

It takes 12 minutes from where you left off: [link]

Template 3 · Send the day before kickoff

The "we're starting tomorrow" ping

Hi [Name] —

Tomorrow we kick off [project]. Excited.

Here's what to expect on the call and what we'll have ready on our side.

See you at [time].

Template 4 · Run before the client kickoff call

The internal kickoff agenda (15 minutes)

[15-MIN INTERNAL SYNC · DAY OF KICKOFF]

1. Recap the brief. (3 min) — What did the client actually say? Pull direct quotes.
2. Identify the landmines. (3 min) — What do they want to avoid? What references do they dislike?
3. Set the plan. (5 min) — Milestone 1, milestone 2, milestone 3, with dates.
4. Assign single point of contact. (2 min) — One person owns client comms. No exceptions.
5. Confirm communication channel. (2 min) — Pull it from the brief. Pin it everywhere.

Template 5 · Send day 5, if onboarding never finished

The stalled-client recovery email

Hi [Name] —

No pressure, just being upfront with you.

Your onboarding is [X]% complete.

To start on the agreed timeline, we'd need the remaining pieces by [day +2 from now].

If that's no longer realistic on your end, totally understandable — just let me know and we'll find a new date.

Why these five, and not more

Every extra automated touchpoint you add past these five starts to feel like pressure instead of service. The post-signature message captures peak excitement. The 48-hour reminder catches the flow before it goes cold. The pre-kickoff ping builds anticipation without asking for anything. The internal agenda makes sure your team shows up as prepared as the client expects. And the recovery email handles the one case the other four can't: a client who's gone quiet mid-flow, without guilt-tripping them into finishing.

If you want the full 5-step onboarding sequence these templates plug into, read how to onboard a new client in 30 minutes. And if the brief itself is where clients usually stall, see the 9-question brief that gets filled out same-day.

See how these fit by profession in the client onboarding guide directory, or automate template 1, 2, and 5 entirely— set up Fentyr and reminders send themselves based on where each client actually is in the flow.

Frequently asked questions

When should I send the onboarding link after a client signs?: Immediately—within the same conversation, ideally before you close the call or the chat window. Excitement is highest right after a "yes," and every hour of delay is an hour the client's attention can drift to something else.
How many reminders should I send if a client doesn't finish onboarding?: Two is usually enough: an automatic nudge around 48 hours after the link goes out, listing exactly what's missing, and a more direct check-in around day 5 if the flow still isn't complete. More than that starts to read as pressure rather than help.
Should the reminder email list what's missing, or just say "please finish"?: Always list specifics. "You still need to upload your logo and sign the contract" gets acted on. "Just checking in" gets archived. If your tooling can auto-generate that list from what the client has and hasn't submitted, use it.
What goes in an internal kickoff agenda?: A short, timed recap of what the client actually said in their brief, the specific things they want avoided, the milestone plan with dates, who owns client communication, and which channel that communication happens on. Fifteen minutes is enough when the brief already captured the details.
