The Pre-Send Deliverability Checklist
Check the audience, infrastructure, message, and monitoring plan before launch.
Confirm SPF, DKIM, and DMARC; verify the visible From address and reply mailbox; clean the audience; and check that the domain and links match the sender identity. Preview text and HTML versions on mobile and desktop.
Send to seed inboxes, test every link, include an opt-out path, and define bounce and complaint thresholds. Record who can pause the campaign. A short checklist prevents small mistakes from becoming large delivery problems.
Apply this guidance to your business context and the rules that govern your recipients. Keep consent or legitimate-interest records, honor opt-outs, and minimize stored contact data.
