Building a 4-email welcome series that converts

For most businesses, the welcome series is the automation with the best return. It makes sense: the moment someone just signed up is exactly when they're most curious and paying the most attention to you. Making the most of that moment with a well-thought-out sequence — instead of letting weeks go by until your next campaign — is one of the most cost-effective things you can do. And the best part: you build it once and it runs on its own for every person who signs up.

In this guide we build it from start to finish, inside arrobaMail's automation editor, so you know exactly where everything lives. Here's the flow we're going to build:

1. What a welcome series is

A welcome series is an automation: a flow that runs on its own whenever an event happens — in this case, a new subscription — with no action needed from you. Instead of a single "thanks for subscribing" email, it's a sequence of emails spaced out over time, each with its own purpose, that takes someone from "just arrived" to "knows your brand and trusts you."

Every flow in arrobaMail is built from three types of pieces: a trigger that kicks it off, actions (send an email, add a tag), and logic (waits, conditions, exits). You combine them in a visual editor. Let's see where it lives.

2. Open the automations editor

In arrobaMail's top menu, go into Automation (it's next to Summary, Subscribers, Campaigns, and Tools). There you'll see your existing flows and the button to create a new one. Create one, give it a clear name — for example, "Welcome series" — and you'll land in the editor.

3. Get to know the editor: palette and canvas

The editor has three zones worth learning right away:

• At the top: the flow's name, its status (Active / paused), and the Save and Pause buttons.
• On the left, the palette: every available block, organized into four categories — Triggers, Actions, Conditions, and Logic. This is where you drag blocks from.
• On the right, the canvas: the space where you drop blocks and connect them to build the flow.

The whole mechanic is that simple: drag a block from the palette onto the canvas, configure it, and connect it to the next one. Let's build the welcome series block by block.

4. Choose the «Subscription» trigger

Every flow starts with a trigger. From the Triggers category in the palette, drag «Subscription» onto the canvas and choose your list. With that, the flow will automatically start every time someone new subscribes.

Important: ideally, that list should receive signups through double opt-in (the person confirms their email before entering). That way your welcome series only reaches real, verified people. How to set that up is covered in subscription forms.

5. Email 1 — the «Send email» action

From the Actions category, drag in «Send email» and connect it below the trigger. This first email goes out as soon as someone subscribes, and its job isn't to sell — it's to welcome them, say thanks, and set expectations for what they can expect from you. A warm tone is worth more than any promotion.

When configuring the action, you can choose a template from your library or generate the email with Amanda AI by describing what you want to communicate. Keep in mind that generating it with AI inside the flow uses up generations, just like in a regular campaign.

6. Add a «Wait»

From the Logic category, drag in «Wait» and connect it after the first email. Don't send the second email right away — let it breathe. Two days is a good starting point. The wait is what turns an annoying burst of emails into a pleasant sequence.

7. Email 2 — your best content

Another «Send email» action, this time with pure value: your best guide, a case study, a genuinely useful resource. This is where you earn the trust you'll need later. Still no direct selling.

8. Emails 3 and 4 with a condition

Repeat the Wait → Send email pattern for the third email (roughly 3 days later), which can now bring in a soft offer: your flagship product or a welcome promo. It's fair game now, because you gave before you asked.

For the fourth — a final nudge — it's best to send it only to people who haven't responded. From Conditions, drag in «Clicked email» and branch: anyone who already clicked goes to an «Exit» (Logic category), and anyone who didn't gets the final reminder. Conditions are what make your flow smart instead of repeating the same thing to everyone.

9. Save and activate the flow

Before turning it on, open the flow's settings (the gear icon) and set its rules: from when it's valid, and whether the same person can re-enter it (for a welcome series, the norm is "once per contact").

Once it's ready, tap Save and set the flow to Active. The system checks that there's at least one trigger and one action. From that moment on, every person who subscribes enters the flow automatically, on their own schedule.

Shortcut: let Amanda build the flow for you

There's a newer capability worth knowing about: on some recent versions of the platform, Amanda AI already assists with — and in some cases generates — the entire automation flow from a well-written prompt. Instead of dragging in each block, you describe what you want — for example: "build a 4-email welcome series for new subscribers, with waits of 2, 3, and 4 days, and have the last one go only to people who didn't open" — and Amanda proposes the flow already built for you to review and adjust.

It's a capability that's still evolving and rolling out gradually, so you may not see it in your account yet. When it is available, it'll be the fastest path from an idea to a working flow — always with the same rule for Amanda: it proposes, you approve. In the meantime, building it by hand with this guide gives you full control and a real understanding of every piece.

10. Measure and adjust

An automation is never "finished" — it gets improved. Watch the metrics at each step — how many open Email 1? Where do people drop off? Which email drives the most clicks? — and adjust whatever needs it: the subject line with the lowest opens, the length of a wait, the order of the messages. How to read those metrics is covered in interpreting reports and metrics.

Common mistakes to avoid

• Selling in the first email. It's the most-read one, and using it to push product burns the relationship before it starts. Give first, ask later.
• Sending everything back to back. Without waits, four emails in one day reads as spam. Timing is part of the design.
• A single welcome email. Better than nothing, but it leaves almost all the value uncaptured. The sequence is what converts.
• Skipping conditions. Sending the "final nudge" to someone who already responded is annoying, and it shows. Branch based on behavior.
