Outbound emails are a crucial part of any referral campaign. They act as the communication bridge between your brand and your participants, keeping them informed, motivated, and engaged throughout their journey.

In this guide, we will help you understand those emails better!

From the moment someone joins your campaign, outbound emails help guide them through what to do next. Whether it's a welcome email that introduces the referral program or a milestone email celebrating their progress, each message keeps participants actively involved and aware of the value of referring others.

Timely and well-crafted emails can significantly boost referral activity. By reminding participants of their referral link, showing how close they are to earning rewards, and encouraging sharing with easy-to-use buttons, these emails increase the chances of users taking action and inviting others.

Referral campaigns often run for weeks or months, and it’s easy for participants to lose interest over time. Outbound emails help maintain momentum by sending regular updates, recognizing achievements, and highlighting what's next—whether it's the next reward tier or a campaign deadline. These nudges keep the excitement alive and participants engaged over the long term.

This is only available in the Universal template. It's for participants who signed up for the referral program.

This is only available in the Universal template as well. It's for participants who joined via an invitation.

Now, you are probably thinking about the difference between the Welcome email, the Organic Signup Welcome Email, and the Referred User Welcome Email, correct?

Don't worry, 😊 we will clarify that for you in the next section!

Now, let's say that you don't want to send to all of your participants the same Welcome email.

Maybe, you want to send different emails depending on how someone joined your referral campaign. Participants who joined on their own (organically) may receive a different email than those who joined through an invitation from another participant.

Keep in mind that you can not TURN ON all 3 Welcome emails in the Universal template.

You have to do something like this:

Or this:

Or even just leave only one of them if you want, like this:

In all cases, you can leave ON the Successful referral email at the bottom if you wish!

These emails are available in Milestone, Newsletter Referral and Universal templates under the Milestones STEP.

You can set them up from here:

Booster emails can motivate participants in your "Tempting Giveaway," "Startup Pre-launch," and "Leaderboard Giveaway" campaigns to continue sharing their unique referral links with friends.
