Yes, but the sending method is not on the Integrations page. Sprwt supports three modes: System Default (Sprwt's own Amazon email service), SMTP (your own mail server or a Gmail app password) and Amazon Ses (your own Amazon account). The mode and the SMTP host/port/user/password fields are internal settings that Sprwt support configures for you during onboarding; ask support if you want to switch.

When SMTP is in use, the sender address does not need Amazon verification - the Email System card treats it as verified automatically. Whichever mode is used, the Email Log shows it in the Protocol column (smtp or ses).
