Actually, you can also with Migadu, for free. You&#x27;ll just get a &quot;Sent via Migadu&quot; signature on the bottom. And almost free without the signature :)<p>However, if you need to send thousands of messages a day, you are probably sending automated mails, transactional or newsletters. Migadu is not intended for that, just as Gmail isn&#x27;t.<p>You don&#x27;t need Mailgun for that either, you can setup your own server to send mails on DO, or go for Amazon SES (Simple Email Service), cost is negligible.
