Pre-send QA report
Email on Acid is a strong inbox-rendering suite. It will tell you how your email looks in 90+ clients. It will not tell you the primary CTA returns a 404, the footer is missing utm_campaign, or the merge tag came through as {{first_name}}.
CheckYourCampaign runs seven QA categories in a single report. Forward a test, the report lands in about 90 seconds, and you get a clean URL the agency can hand to a client without forcing them through a login.
