Preview delivered ESP campaigns across email clients and test where they land with MailSlurp device rendering and inbox placement tutorials.
Use these provider-specific tutorials to check a finished campaign after it leaves your email service provider. MailSlurp can render the delivered email across selected clients and devices, then separately measure whether the campaign reaches inbox, promotions, spam, or is not received at controlled provider addresses.

Choose the right campaign check
- Use device previews to inspect responsive layout, images, buttons, typography, footers, and dark mode after the ESP sends the email.
- Use inbox placement testing to measure where the same campaign lands across controlled provider inboxes.
- Use Email Audit for content, link, image, and accessibility findings.
These checks answer different questions. Run device rendering and inbox placement against the final campaign revision before an important send.
