You’ve set up your form, but you notice that it is not working. Perhaps the Subscribe button doesn’t take any action, the confirmation email is not being sent or subscribers are not being added to the assigned group after signing up.
To start troubleshooting your form, make sure you check the following on the Forms page:
If it’s a pop-up or a promotional form, make sure it is active. If it's paused, simply toggle the switch to green.
There should be at least one group assigned where subscribers will be added upon sign-up. If there isn’t any assigned group, the form will not add any subscribers to your list.
Click on the Overview button of the form.
Click on Edit groups on the Groups section.
If double opt-in is active, then the subscriber should first confirm their subscription via the confirmation email sent to them before they can be added to your list. Confirmation emails are sent once to the same subscriber every 24 hours.
Check that there is a valid sender's email address. If there isn’t one in place, then the confirmation email will never be sent.
Click on the Double opt-in tab.
Under the Confirmation email tab, on the Sender row, check if there is a valid email address. If there isn’t one, click on Edit.
Inside the confirmation email, variables shouldn’t have any spaces, the wrong brackets or any weird formatting. Click on Edit to customize the confirmation email.

Test emails
To test your form, we recommend using variations of your email to create unique testing addresses that will receive emails to the same original inbox. To do this, simply add a + sign at the end of their email prefix, for instance:
example@mailerlite.com can become example+1@mailerlite.com, example+2@mailerlite.com, example+3@mailerlite.com, and so on.
If these additional addresses are used to test your forms, the confirmation email will still land in the original inbox, but MailerLite will recognize each email as a separate subscriber, so you can test your forms without creating additional inboxes.
If you are still having trouble with confirmation emails after trying the above steps, check MailerLite's support options.
