MailerLite variables put each subscriber’s own referral link into a single campaign or automation.

GrowSurf MailerLite tutorials MailerLite variables help

With GrowSurf syncing into a MailerLite Group, each subscriber’s referral link and progress are fields. One campaign then covers the whole Group, each reader seeing their own link.

MailerLite variables take the form {$name}. The dollar sign is part of the syntax, not decoration.

Integration Steps

Confirm the fields are populated

The MailerLite API key field in the GrowSurf Program Editor — MailerLite lives in Program Editor > 4. Options > Integrations.

Open a synced subscriber in MailerLite and check the GrowSurf fields before building the campaign.

Show the link, do not hide it in a button

Use {$grsf_share_url} as both the href and the visible text. Readers copy URLs they can see.

Add progress for people who have some

{$grsf_total_referral_count} and {$grsf_next_milestone} personalize the ask. Keep the sentence readable for a subscriber at zero, because most of the Group is.

Reuse it in an automation

The same variables work in MailerLite automation emails. A referral prompt a week after signup keeps working without you sending anything again.

Code Snippets

The referral link

<p>Share your referral link:</p>
<a href="{$grsf_share_url}">{$grsf_share_url}</a>

Progress and next milestone

<p>You have made {$grsf_total_referral_count} referrals so far.</p>
<p>{$grsf_next_milestone}</p>

A share button

<a href="https://twitter.com/intent/tweet?url={$grsf_share_url}">Share on X</a>

Tips

Keep the dollar sign

{$grsf_share_url}. Without $ the variable renders as plain text.

Referral status has an unusual name

In MailerLite it is {$grsf_participant_referral_status}. Copy it from the table rather than guessing from the other fields.

Test against a synced subscriber

A preview using an address outside the Group resolves nothing.

FAQ

What is the variable syntax?

{$name}, for example {$grsf_share_url}.

Do variables work in automations?

Yes, the same as in campaigns.

Why is my referral link blank?

Either the subscriber has not synced, or the variable is missing its dollar sign.
