How to Send Bulk Emails with Thunderbird

Thunderbird has a maximum number of recipients around 60 per email, so it’s not optimized to send bulk emails. To work with a large mailing list, use a specialized bulk email service.

There are two ways to send bulk emails.

The first option is to manually add multiple recipients to an email in Thunderbird. However, the number of recipients is limited to only around 60 per email, so you’d better choose an alternative option.
