## FAQ

### Is Unitpost a MailerSend alternative?

Yes, for apps that want transactional and marketing email in one product, idempotent sends and a free plan without a card. MailerSend is a good fit for a small project on its $7 plan, or for US and Canada SMS and WhatsApp next to email.

### Does MailerSend send newsletters?

It has a bulk send endpoint, but MailerSend recommends MailerLite, its sister product, for newsletters and campaigns. Unitpost sends both from one account and one contact list.
