Get startedFAQs
Your email quality assurance standards should cover content, rendering, accessibility, deliverability, audience, and compliance in one documented review. The review should cover:
- Content: Check the copy, personalization, subject lines, and preview text for errors or truncation.
- Functionality: Verify links, calls to action, images, tracking pixels, and unsubscribe options.
- Rendering: Preview the email across all major email clients, devices, operating systems, and in dark mode.
- Accessibility: Review the alt text, color contrast, and support for people with color vision deficiencies.
- Deliverability: Test content users might interpret as spam, sender authentication, and inbox placement before you send.
- Audience and compliance: Confirm the recipient list, suppression rules, consent requirements, and send details.
Validity Engage brings these checks into one automated workflow and offers guidance for resolving any issues you find before you hit send.
The return on investment (ROI) of an email QA workflow can include faster testing, fewer errors, and more consistent email campaigns. Validity customers have reported a 50 percent reduction in QA time and a 68 percent decrease in email error rates. Validity Engage can also reduce manual work and expenses by combining creation, testing, deliverability insights, data quality, and live monitoring on one platform.
Email QA can protect your sender reputation by spotting issues that may cause bounces, blocklistings, or bad subscriber experiences before you actually send the email. It makes sure your links go to the right page, your code is correct, your tracking pixels are working, your subject lines aren’t too promotional, and that nothing should trigger spam placement. Validity Engage also gives you inbox placement insights and monitors the emails you've sent, helping your team find and fix issues throughout the campaign's lifecycle.
