A welcome series is the set of emails a new subscriber gets in their first days, starting the moment they join, that delivers what they signed up for and shows what to expect next.
How it works
The signup starts it, and the first email goes straight away. A common shape:
- Right away: deliver what they signed up for (the guide, the discount, the first issue) and say what's coming and how often.
- A day or two later: your best piece of work, or the story of why you do this.
- A few days after that: the next step, such as a product, a reply or a reading list.
Where someone signed up can change the series. A podcast listener and a buyer from your store may want different first emails.
Why it matters
- It's the moment people remember signing up. A new subscriber knows who you are and why they joined.
- It sets expectations. Saying what's coming and how often makes later emails look familiar, not like spam.
- It runs for everyone. Each new subscriber gets the same good start, whenever they join.
How Mimeo handles it
In Mimeo a welcome series is a flow and a sequence. Your site sends an opted_in event when someone joins (opt-in intake). A flow triggered on that event starts the welcome sequence and waits for it to finish. The first step, with no delay, sends the moment they start. The trigger can match on the event's details, so details.entry_point can route podcast signups to a different series. Set the run policy to single run ever, so someone who resubscribes doesn't start the series again.
Moving an existing list doesn't welcome everyone a second time. A CSV import is treated as history by default, and history triggers nothing (historical imports). To keep a promotional broadcast from landing in the middle of the series, a guard can hold it for people still in the sequence. See Mimeo terms for flows and sequences in Mimeo's own words.
