I need help tweaking my current mail-sending setup so that every outgoing message shows a sender address on my own domain instead of the default one my system now adds. Nothing else in the message needs to change—just the “From” field must display the custom-domain email I provide. You’ll look at the code or service that dispatches the emails, adjust the SMTP or API settings accordingly, and verify that the new address appears correctly in major clients (Gmail, Outlook, Apple Mail) without triggering spam or spoofing warnings. SPF, DKIM, and DMARC records are already in place; update them only if the change requires it. Once finished, send me a short note describing what you modified and a test message that proves the new sender email is live and authenticated.

Right now the issue is not email content or deliverability overall, but sender identity: your system is overriding the From address, and that needs to be corrected without breaking authentication alignment. I’d trace the exact dispatch layer first—whether this is happening in SMTP config, an API mailer, or application code—then update it so your custom-domain sender is used cleanly and still passes properly in major inboxes. I’ve handled sender-address fixes, SMTP/API mailer adjustments, and DNS-alignment checks for transactional email setups where the main risk is creating spoofing or spam warnings while trying to “force” a From address. Since SPF, DKIM, and DMARC are already in place, this should be a focused cleanup rather than a broad mail setup job. To make this efficient, I’ll also send you a short change note and proof test once done. - What service or app is currently sending these emails? - Are the emails going out through SMTP credentials or an API provider like SendGrid, Mailgun, SES, etc.? - Do you want the visible From name changed too, or only the email address itself?

The part most people miss is that the SMTP envelope sender must match the custom From address to avoid spam filters. I'll edit the mailer code to set both the header and the envelope to the domain you provide, then test the API call. A quick DNS check will confirm SPF and DKIM still align after the change. A common mistake is leaving the 'reply-to' field unchanged, which can cause Outlook to show the default address. You’ll see the new address appear correctly in Gmail, Outlook and Apple Mail without any spoof warnings. I’ll send a short note with the exact changes and a test email that passes DMARC.
