A welcome series is a short run of automated emails that a new subscriber or customer receives in the days after they sign up. It typically starts with one email sent straight away and continues with two to five more spaced over a week or two. Its purpose is to confirm the sign-up, deliver whatever was promised, and introduce the business while interest is at its highest.
How a welcome series works
The sequence starts when someone joins a list, usually through a sign-up form, a checkout opt-in or a download. Your email platform’s automation then sends each message after a set delay, and can skip or branch depending on what the person does. Someone who buys after email two might jump to a customer path; someone who has not opened anything might get a shorter version.
A common shape for a UK service business looks like this:
- Immediately: confirm the sign-up, deliver the guide or discount that was promised, and say what emails will follow and how often.
- Day two or three: the problem you solve and how you approach it, written for the person who signed up, not for the business.
- Days five to seven: evidence that helps them decide, such as how the service works, prices or a useful answer to a common question.
- Day ten or so: a clear next step, such as booking a call, visiting a shop or making a first order.
Why it matters
The days after sign-up are when people remember who you are and why they gave you their address. Emails sent then tend to get far more attention than a newsletter that arrives three weeks later from a name they no longer recognise. A good series turns a passing interest into a relationship; a missing one leaves new subscribers cold until your next campaign.
It also sets expectations, which protects you later. People who are told at the start what they will receive, and how often, are less likely to unsubscribe or press the spam button when it arrives. In the UK, the series also has to sit on a lawful basis. Under PECR, marketing emails need consent or, for existing customers, the soft opt-in, and every message in the series needs a working unsubscribe link.
Common mistakes
- Making the first email a generic “thanks for subscribing” with no content and nothing promised delivered.
- Pushing a sale in every email from the first minute, before the reader knows anything about you.
- Leaving the series unchanged for years, so it mentions old prices, past events or staff who have left.
- Sending the series and the regular newsletter at the same time, so a new subscriber gets four emails in three days.
- Adding customers who bought once, and never ticked a marketing box, to a promotional series without checking whether the soft opt-in applies.
How to act on it
Write down what someone who signs up actually wants, then plan each email around one job. Deliver the promised lead magnet in the first message, keep the sender name consistent, and tell people what is coming. Hold new subscribers out of regular campaigns until the series finishes, so they get a sensible pace.
Review the series every quarter: open and click activity per email, the unsubscribe rate on each message, and how many people take the final step. Fix the weakest email first. If you are not sure what the series should lead to, or how it fits with your other channels, a digital marketing strategy and consulting engagement can plan the sequence alongside the rest of your marketing.
