-
Send transactional email
Send the order-confirmation template to this customer with their order number and total, then confirm it was delivered. -
Debug a failed delivery
Find every email that failed yesterday, group them by bounce reason, and tell me what needs fixing. -
Check production readiness
Is my sending domain ready for production? Check the DNS records and tell me what's still missing. -
Send a batch
Send this release note to these 40 beta testers as a bulk batch and report any that failed. -
Test before anyone sees it
Send the new password-reset email to my Mailtrap sandbox, then tell me the spam score and any HTML that won't render in Outlook. -
Triage the inbox
Summarize the newest threads in my support inbox and draft replies for the ones about billing.
