It is possible to connect your Sendgrid, Mailgun, Amazon SES, and other SMTP providers to Instantly, by using SMTP from these providers and IMAP from your email provider.
You will need an IMAP inbox in order to connect SendGrid/Mailgun/other with Instantly. We need that in order to support all features.
Most of our customers use their Gmail account as the IMAP target (for receiving emails) and then use SendGrid/Mailgun information for SMTP (for sending emails).
Note: Using this connection with Outlook accounts is not possible as Outlook/Microsoft accounts can only be connected via the oAuth Microsoft connector.
