What syncs between Viral Loops and Mailchimp?

Participants join your audience, with their referral link as a merge field.

Viral Loops to Mailchimp

Their personal referral link, for any email you send

How many friends they've referred so far

Mailchimp to Viral Loops

New subscribers
Join your program automatically, with their own referral link
Audience import
Brings the people already on your list into the program
Unsubscribes
Stop your campaign emails to them, without removing them from the program

One campaign connects to one audience. If your audience requires any field beyond email, first name and last name, the sync fails, so make the others optional first.

What can you do with Mailchimp and Viral Loops?

  1. 1

    Put every reader's link in your newsletter

    Add the SHAREURL and REFERRALS merge tags to your Mailchimp template, and each subscriber sees their own link and count in every issue.

  2. 2

    Email people when they reach a reward

    Build a Mailchimp segment on REFERRALS, for example 3 or more, and send the reward email from Mailchimp in your own design.

  3. 3

    Give your whole list a link on day one

    Import your audience when you launch. Everyone already subscribed gets a referral link, and new subscribers get one as they join.

FAQ

Mailchimp FAQ

Which merge tags does Viral Loops add to Mailchimp?

SHAREURL for the referral link, REFERRALS for the referral count and REFCODE for the referral code. REFEMAIL, REFFNAME and REFLNAME say who referred them, and giveaways add leaderboard tags like RANK. In an email you write them as *|SHAREURL|*.

Do my existing subscribers get a referral link?

Yes. Import your audience from the Viral Loops dashboard and each subscriber joins your program with a referral link. New subscribers join automatically.

What happens when someone unsubscribes in Mailchimp?

They stop getting your campaign emails but stay in your program. It works one way: unsubscribing in Viral Loops doesn't unsubscribe them in Mailchimp.

Why did my Mailchimp sync fail?

Usually because the audience requires a field other than email, first name and last name. Make the extra fields optional in Mailchimp and the sync goes through.

Can I send the referral emails from Mailchimp instead?

Yes. Turn off the Viral Loops notification emails and send your own from Mailchimp, with the merge tags filling in each person's link and count.
