Using our SMTP-only plan or SendGrid/Brevo/MailGun integration you can connect your SMTP-only account.
Please note, that for our SMTP-only options, we have a special Send-only pricing. The trial, Basic, Pro, or MAX plans will not work with our SMTP options as they work with inboxes that can send and receive emails (SMTP/IMAP).
During the trial, Basic, Pro, or MAX plan you can connect the SMTP-only account only when creating an IMAP connection. The email address for the IMAP connection must be the same email address as the one you specified in the SMTP.
Note: this option doesn´t work with Office365 inboxes as they don´t support IMAP.
