Switching between transactional email tools is generally possible but involves migration effort: exporting your data or configuration from SendGrid, re-importing or reconfiguring in Brevo SMTP, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Brevo SMTP on a non-production project first before migrating.
