Frequently askedquestions

Why does MailerLite refuse the campaign?
MailerLite accepts e-mail content from apps only on its Advanced plan. On other plans the post fails with a message saying so.
Which sender does the e-mail use?
The sender name and e-mail you entered when connecting. The e-mail must be verified as a sender in MailerLite.
Who receives it?
The group you pick in the MailerLite options of the post. Without a group, MailerLite's default audience.
Is there a free trial for MailerLite?
Yes, every new account starts with a 7-day free trial. We ask for a card to start the trial, but we don't charge anything during it. After that the Basic plan is available from $19 a month, and you can cancel anytime.
