The member, added or updated
Each approved conversion with an email adds the person to your audience with the status you chose, or updates them if they are already there. Existing members keep their status.
Mailchimp
Mailchimp link tracking that tags converters by the link they used
Letlink records clicks on the short links in your campaigns and, when a click converts with an email address, adds the person to your Mailchimp audience with tags for the event and the short link, plus an event on their timeline.
Short answer
The Letlink Mailchimp integration adds the person behind each approved conversion to your Mailchimp audience, tags them with the kind of conversion and the short link that brought them, and records a custom event on their profile. It sends conversions only — a click has no email address — and new contacts are added by double opt-in unless you choose otherwise. It is on Growth at $8.90 a month and Ultimate at $39.90.

Features
What reaches your Mailchimp audience
Tagged by event and link
Two tags per conversion: one for the event — sale, lead, signup or your custom name — and one for the short code, so a segment of everyone who bought through spring-sale is one filter away.
A timeline event
A custom event such as letlink_sale is recorded on the profile with short_code, value, currency and order_id, ready to trigger a Customer Journey.
Three ways to add people
Double opt-in, the default, emails new people a confirmation and keeps them pending until they confirm. Subscribe directly is for flows that already collected consent; transactional adds them without making them marketable.
Your own tag prefix
Tags and events start with letlink unless you set another prefix, so they sort together and never collide with your own tags.
Clicks in your Mailchimp campaigns
Short links in a Mailchimp email are recorded click by click with time, country, device and referrer. Letlink does not see opens — only clicks on links.
Use cases
Segments people build with it
Buyers by product link
Everyone tagged with a product’s short code gets the care guide and the reorder reminder for that product, not the rest of the catalogue.
Journeys started by a conversion
The letlink_signup timeline event starts an onboarding journey the moment a sign-up is reported.
Partner and influencer cohorts
Converters tagged by each partner’s link show which partner’s audience keeps opening your emails later.

What does the Letlink Mailchimp integration do?
It adds the person behind each approved conversion to your Mailchimp audience, tags them with the event and the short link that brought them, and records a custom event on their timeline. Only conversions reported with an email address are sent; clicks are not. It is on Growth at $8.90 a month and Ultimate at $39.90.
Can Letlink track clicks in Mailchimp emails?
Yes. Put a Letlink short link in the campaign and each click is recorded with time, country, device and referrer, on every plan including Free. Letlink does not track email opens and does not identify which subscriber clicked; it records what clicked, not who.
Will people be subscribed without confirming?
Not by default. New contacts are added by double opt-in, so Mailchimp emails them a confirmation and they stay pending until they confirm. Choose Subscribe directly only if the conversion flow already collected marketing consent, or Transactional to add them without making them marketable.
Which tags does Letlink add?
Two per conversion: <prefix>-<event>, where the event is sale, lead, signup or your custom name, and <prefix>-<short code>. The prefix is letlink unless you change it. The matching timeline event is <prefix>_<event> with short_code, value, currency and order_id.
Why is a timeline event missing for a new member?
Mailchimp runs the batch in the background and does not guarantee the order of its operations, so for someone brand new the event can occasionally be skipped. The member is always created with its tags. Errors such as a previously unsubscribed address are not reported back to Letlink.
