Sendex not working

Getting Started

Hello. Guys, the problem is with Sendex.
In the subscription form, I enter email, I click “subscribe” - I get a message - “A letter with a confirmation link has been sent to the specified email address.”

The letter does not arrive, there are no subscribers in Sendex.
Call on page [[!SendexEventTracking]] [[!Sendex? &id=1]]
Thanks for the advice

Can you successfully send emails with other extras?

Maybe you can install QuickEmail to test if there is a general problem with your email settings.

Thank you. Tried already.
The reason is found on the hosting.
