Connect Contact Form 7 to Moosend and every form submission becomes a subscriber in the Moosend mailing list you choose. ClickSyncr for Moosend adds a ClickSyncr Moosend tab right in the Contact Form 7 editor: connect your API key once, pick a mailing list, map your fields, save. No code and about two minutes per form.
You need three things: the ClickSyncr for Moosend plugin activated, Contact Form 7 active, and a Moosend account with permission to create an API key. The key is stored once and shared across every supported builder on the site.
Treat the key like a password. Anyone holding it can read and modify your Moosend audience.

Every builder maps the same schema: Email (required), the standard Name field, and the selected mailing list’s custom fields (phone, company and any you define), mapped by their Moosend names with each field’s type shown, including number and date types. Moosend matches subscribers by email, so a repeat submission updates the same subscriber instead of creating a duplicate. An unmapped field is simply skipped and never overwrites existing data with a blank value.
The form’s subscriber status controls Moosend’s confirmation email directly: Added right away skips it, and Use list setting lets the mailing list’s own Moosend double opt-in decide. Fields are per list too: pick a mailing list and the mapping rows show that list’s own custom fields, with number and date types marked.
Submit the form on the front end (not the admin preview) with a test address you can recognise, filling every mapped field. In Moosend, open the mailing list and search for your test address under its members. With Use list setting on a double opt-in list, the subscriber appears after they click Moosend’s confirmation email. Back in WordPress, the ClickSyncr entry in the admin bar shows per-form sync counts and the last error, if any: a quick pulse check without leaving the site.
| Symptom | Cause and fix |
|---|---|
| Lists don’t load after pasting the key | Copy the key from More → Settings → API key in Moosend and paste it exactly. |
| The subscriber never appears | If the consent box was left unticked, or the form’s status is Not synced, nothing is sent to Moosend by design. On a double opt-in list with Use list setting, they appear only after clicking the confirmation email. |
| A custom field stays empty | Fields are per list. Check the mapping row and confirm the field exists on the mailing list you selected, with a compatible type. |
| Sync stopped working | Check the admin-bar health menu for the last error. An invalid or rotated API key is the usual cause; paste the new key in any builder and it updates everywhere. |
No. ClickSyncr for Moosend stores one account API key for the whole site, so every form and every builder shares the same connection. Each form still chooses its own mailing list and field map.
Yes. Every form carries its own ClickSyncr Moosend setup, so each one picks its own mailing list and mapping.
