Welcome Series
Email MarketingAlso: Welcome Sequence · Onboarding Email Series
Quick definition
A welcome series is a set of automated emails sent to someone right after they subscribe, sign up or make their first purchase. It introduces the brand, sets expectations and moves the new contact toward their next useful action. Usually three to five emails spread over the first one to two weeks.
How it varies across Australia
Welcome series consistently outperform every other email type on open rate and click-through rate across Australian brands, ecommerce and B2B alike. The gap between a welcome series and a standard newsletter send is usually wide enough that skipping one is a genuine missed opportunity, not a minor gap.

New subscribers pay attention in a way they never will again. The moment someone hands over their email address, curiosity is at its peak. A welcome series exists to use that window before it closes.
Most brands treat the welcome series as a formality. One email, a discount code, done. That's a missed opportunity. A proper welcome series does three things across three to five emails: introduces who you are and why you're worth the inbox space, sets expectations for what emails they'll get and how often, and nudges toward a specific next action, whether that's a first purchase, booking a call or exploring a feature.
The segmentation question matters here too. A welcome series triggered by a newsletter signup should read differently to one triggered by an abandoned signup form or a first purchase. Treating every new contact the same way flattens the personalisation that makes welcome series work in the first place.
Done well, a welcome series does more heavy lifting for retention than most standalone campaigns. Done badly, it's just another email the subscriber ignores before they unsubscribe.
The welcome series is the only email a new contact actually expects. Waste it on a discount code and you've wasted the best attention you'll ever get from them.
How it shows up
A welcome series shows up as the automation flow triggered by a new subscriber tag, a signup form completion or a first order in your email platform. It shows up in reporting as a separate campaign type from broadcast newsletters, usually with its own open rate, click-through rate and conversion rate that should sit well above your average.
It also shows up in churn data. Contacts who never received a proper welcome series or who received a badly timed one tend to unsubscribe or go inactive sooner than contacts who went through a considered sequence.
The Australian context
Under the Spam Act, any welcome email needs a clear identification of the sender and a functional unsubscribe link, same as every other commercial email. What trips up Australian brands more often is timing expectations. If someone signs up expecting a one-off discount code and instead gets five emails over two weeks, that mismatch drives unsubscribes and, occasionally, spam complaints to ACMA. Be explicit early in the series about what's coming and how often.

Common questions
How many emails should a welcome series have?
Three to five is the usual range. Fewer than that and you don't have room to introduce the brand and set expectations. More than that and attention drops off before the sequence finishes. Test length against your own completion rates rather than copying a default.
When should the first welcome email send?
Immediately, or within minutes of signup. Attention is highest right at the moment someone subscribes. Delaying the first email by even a day loses a meaningful chunk of the curiosity that made them sign up.
Should a welcome series include a discount code?
It can, but not in the first email. Let the opening message establish who you are first. A discount later in the sequence, once some value has been shown, converts better than leading with the offer and teaches better subscriber habits.
Is a welcome series the same as onboarding?
They overlap but aren't identical. A welcome series is specifically the email sequence after signup. Onboarding is broader and can include in-app guidance, product tours and support touchpoints beyond email. The welcome series is one piece of a full onboarding experience.
