External SMTP - number of logins/campaign


New Member

please help me to see this:
if I send 500 emails from one external SMTP account, Mailwizz will log in 500 times to the SMTP server?

(A few months ago when we used an email sending service our campaign was regularly stopped because the external SMTP provider's server returned an error message after a while due the high number of logins. I'd like to see it right at the beginning so we can plan/change the campaign/email account provider accordingly. )

Thanks in advance.

You can configure your delivery server to send more messages per connection, there's a setting for this in the delivery server itself, however, keep in mind that this will not always work as expected.
