TL;DR: There are six emails every B2B onboarding needs: a welcome, a kickoff invite, an information request, a nudge when the customer goes quiet, a go-live note, and a 30-day check-in. Below are copy-paste templates for each. They're written to be sent by a person and anchored to one shared onboarding plan, not blasted as a drip campaign.
Customer onboarding email templates are the reusable messages an onboarding manager or customer success manager (CSM) sends to walk a new B2B customer from "signed" to "live and getting value." The best ones aren't marketing drip sequences fired by a tool – they're real, human emails tied to a shared onboarding plan, so every message points the customer back to the same place instead of scattering context across their inbox.
This is the set of six that covers a full onboarding: welcome, kickoff invite, information request, nudge, go-live, and 30-day check-in. Each comes with a copy-paste template you can adapt. They work for any B2B software or services motion – SaaS platforms, implementation-heavy tools, agencies onboarding retainer clients. We'll use Valuecase – a customer onboarding platform where each customer gets their own branded, shareable Space (the single place they open to onboard, no login required) – as the running example of what these emails should link to instead of an attachment pile. For the wider process, see how to onboard B2B SaaS customers.
The onboarding email sequence at a glance
Six emails, and roughly when each one goes out:
- Welcome – the moment the deal is signed. Confirm the outcome, set expectations, and share the onboarding plan.
- Kickoff invite – within a day or two. Book the kickoff call and preview the agenda.
- Information request – right after kickoff. Ask for the data, files, and access you need to build.
- Nudge – whenever the customer goes quiet on an open task. A gentle, specific chase.
- Go-live – when the customer reaches first value. Celebrate it and point to what's next.
- 30-day check-in – a month in. Confirm adoption is sticking and hand off to customer success.
Two principles hold across all six. First, every email is sent by a named person, not a no-reply address – onboarding is a relationship, and these read like one human writing to another. Second, every email points back to one shared plan, so the customer has a single source of truth rather than a dozen threads to dig through. The only part worth automating is the chasing – reminders on open tasks – and even those link back to the same human-run plan (more on that at the end).
Welcome email template
Send this the moment the contract is signed, while momentum is highest. The job is to confirm what the customer bought, set expectations for what's next, and hand them the shared plan so onboarding has a home from minute one.
Subject: Welcome to [Product] – here's your onboarding plan
Hi [First name],
Welcome aboard, and thanks for choosing [Product]. I'll be your main point of contact through onboarding, and my job is to get you from today to [the specific outcome they bought] as smoothly and quickly as possible.
I've set up a shared space for your onboarding – it has your plan, the tasks on both sides, and everything you'll need in one place: [link to Space]. No login required; just open the link.
Next step is a short kickoff call so we can align on your goals and timeline – I'll send a couple of times separately. In the meantime, take a look at the plan so nothing's a surprise.
Looking forward to it,
[Your name]
Kickoff invite template
Send this within a day or two of the welcome. Book the call, preview the agenda so the right people show up prepared, and reinforce the shared plan. For how to run the call itself, see how to run a customer onboarding kickoff call.
Subject: Let's book your [Product] kickoff
Hi [First name],
Ready to kick things off. The kickoff is a 30-minute call where we'll confirm your goals, walk through the plan, and agree on the timeline to [outcome].
Here's a link to grab a time that works: [scheduling link].
So the call is useful, it helps to have [relevant stakeholder / decision-maker] there too – onboarding tends to move faster when everyone who'll use [Product] is aligned from the start. The agenda and plan are already in your space: [link to Space].
Talk soon,
[Your name]
Information / document request template
Send this right after kickoff. This is the stage where onboarding most often stalls, because progress depends on the customer doing things. The fix is to ask through a structured form rather than a long email list, so nothing gets lost and you're not chasing replies one at a time. For the tactics, see how to collect customer information during onboarding.
Subject: A few things we need to get [Product] set up
Hi [First name],
Great kickoff – thanks to you and the team. To start building your setup, we need a few things from your side. I've put them in a short form inside your space so it's easy to complete in one go and nothing gets buried in email: [link to Space / form].
It should take about [X] minutes. Once it's in, we'll begin configuration and you'll see progress in the plan.
If anything's unclear or you'd rather walk through it live, just reply and we'll find time.
Thanks,
[Your name]
Nudge / gentle-chase template
Send this when a customer goes quiet on an open task. The tone is helpful, not nagging – reference the specific task, make it easy to act, and offer a hand. Keep it short.
Subject: Quick nudge on [task]
Hi [First name],
Just a gentle nudge – [task, e.g. "the data upload"] is still open on your side, and it's the one thing holding up [next step / go-live]. It's quick to complete here: [link to task in Space].
If something's blocking it, tell me what and I'll help clear it – happy to jump on a quick call if that's easier.
Thanks,
[Your name]
Go-live / "you're live" template
Send this when the customer reaches first value – not just when the switch is flipped, but when they've hit the outcome they bought the product for. Mark the milestone, and point to what's next so momentum carries into adoption.
Subject: You're live on [Product] 🎉
Hi [First name],
You're officially live – [the outcome, e.g. "your team is set up and your first campaign is running"]. Nice work getting here.
Here's what's next to get the most out of [Product]: [1-2 next steps]. They're already queued in your plan: [link to Space].
I'll check in around the 30-day mark to see how it's landing, but I'm one reply away before then if anything comes up.
Congrats again,
[Your name]
30-day check-in template
Send this about a month after go-live. Confirm adoption is sticking, catch any friction before it becomes a churn risk, and set up the handoff to ongoing customer success. For how to run that transition, see the sales-to-customer-success handoff.
Subject: How's the first month with [Product]?
Hi [First name],
You've been live about a month – how's it going? I'd love to hear what's working and where there's still friction.
A couple of things I noticed in your usage: [specific observation / opportunity]. Worth a quick chat if you're up for it: [scheduling link].
Going forward, [CSM name] will be your ongoing point of contact – they've got full context on your setup and goals, so nothing gets lost. I've looped them in on your space.
Thanks for a great first month,
[Your name]
Stop sending these by hand: automate the chase, keep the emails human
Here's the line worth holding: the emails above are meant to be written by a person, because onboarding is a relationship and it reads that way. What you should automate is the chasing – the reminders on open tasks that otherwise eat a CSM's week. When a task sits open in the customer's shared plan, an automated reminder can nudge them on it, so your team isn't manually re-sending the "gentle nudge" above every few days.
In Valuecase, that's exactly how it works: each customer's onboarding lives in their own branded Space, automated reminders chase them on open tasks, and an engagement score flags accounts that have gone quiet so you know who actually needs a human follow-up. The AI layer can go further – drafting the follow-up, scoring which onboardings are at risk this week, and prepping the next update – all pointing back to the shared plan a person still owns. Concrete starting points are in the AI use-case library: drafting a follow-up email and chasing stalled onboardings with context. For the broader tactics on rescuing quiet accounts, see how to catch stalled onboardings before they churn.
The result: the customer gets human, personal emails at the moments that matter, and your team stops burning hours on manual chasing.
FAQ
What emails do you send during customer onboarding?
Six cover a full B2B onboarding: a welcome (at signature), a kickoff invite (within a day or two), an information request (after kickoff), a nudge (whenever a task goes quiet), a go-live note (when the customer reaches first value), and a 30-day check-in (to confirm adoption and hand off to customer success). Each should be sent by a named person and link back to one shared onboarding plan rather than piling up attachments.
How do you write a welcome email to a new customer?
Send it the moment the deal is signed. Confirm the specific outcome the customer bought, introduce yourself as their point of contact, set expectations for what happens next, and – most importantly – hand them the shared onboarding plan so the process has a home from day one. Keep it warm and human; a welcome email is the first impression of your onboarding, not a marketing blast. Use the copy-paste template above as a starting point.
How do you follow up when a customer goes quiet during onboarding?
Reference the specific open task rather than sending a generic "just checking in," make it one click to act on, and offer to help clear whatever's blocking it. Keep it short and friendly. Better still, let automated reminders handle the routine chase on open tasks so your manual follow-ups are reserved for accounts that genuinely need a human – which is where an engagement signal that flags quiet accounts earns its keep.
