**My software**  
My Mautic version is: 6.0.3  
My PHP version is: 8.1.34  
My Database type and version is: MariaDB 10.11.16

**My problem is:**

I am able to send and receive Test Emails from the Email (Configuration) page - and when I send e-mail directly to a test contact from the Contact’s detail view, I receive that too.

I’ve tried this on two separate SMTP servers, one from a shared hosting provider and one from a VPS provider. No problems there.

But when I enter my e-mail address in my homepage’s “subscribe” form all I can see happening in the Mautic dashboard is the contact’s segment is modified to “pending opt-in.” I’ve tried a few dozen times at this point and nothing has resulted in the e-mail being sent.

**These errors are showing in the log:**

The Mautic error log is empty.

**Steps I have tried to fix the problem:**

I’ve double-checked that the e-mail is set to “Transactional” and not “Marketing” within the Campaign Builder.

I’ve ensured contacts are able to re-initiate the campaign.

The campaign is active, the contact is not on a DNC list (I can see the Email channel is active in the test contact’s preferences.)

I also tried deleting and rebuilding the entire campaign but nothing has changed.

Hello,

Is this a fresh setup? Have you ever sent an email through the system as scheduled or campaign?

Joey

Thanks for your reply.

I had sent successful test e-mails and was really scratching my head as to why these were failing, and wanted to share the outcome in case anyone searches this topic in the future.

It turns out the campaign was listening for a “form” when in fact it should have been listening to a “segment” instead, as the API was adding people to a segment. I had delivered the Mautic Form HTML to another developer who proceeded to use the API instead and assumed I understood the implications, which I did not. Hope this helps someone.
