Once GrowSurf syncs into a Mailjet list, each contact’s referral link and progress are stored contact properties. Mailjet reads them with [[data:...]], so one campaign serves the whole list.

Mailjet has more than one variable form, and picking the wrong one is the usual reason a referral link comes out blank.

Integration Steps

Check the properties are there

The Mailjet API key and secret key fields in the GrowSurf Program Editor — Mailjet lives in Program Editor > 4. Options > Integrations.

Open a synced contact in Mailjet and confirm the GrowSurf properties carry values before you build the campaign.

Use the data form, not the var form

GrowSurf writes contact properties stored on the contact, which Mailjet reads with [[data:...]]. The var: form is for values passed in at send time and will not find them.

Show the link

Use [[data:grsf_share_url]] as both the href and the visible text, high in the email.

Keep the offer editable

Reward amounts and milestone copy live in GrowSurf. Change them there and the next sync updates every Mailjet contact without an edit to the campaign.

Code Snippets

The referral link

<p>Share your referral link:</p>
<a href="[[data:grsf_share_url]]">[[data:grsf_share_url]]</a>

Progress and next milestone

<p>You have made [[data:grsf_total_referral_count]] referrals so far.</p>
<p>[[data:grsf_next_milestone]]</p>

A share button

<a href="https://twitter.com/intent/tweet?url=[[data:grsf_share_url]]">Share on X</a>

Tips

`data:`, not `var:`

Stored contact properties use the data form. The var form belongs to values supplied in a send call.

Double brackets, no spaces

[[data:grsf_share_url]] exactly as written.

Test to a contact on the list

A test send to an address outside the list cannot resolve stored properties.

FAQ

What is the syntax for the referral link?

[[data:grsf_share_url]].

Why does `var:` not work?

That form reads values passed in at send time. GrowSurf stores properties on the contact, which the data form reads.

Which property should always be in the email?

The share URL.
