Mailchimp email preview questions

What to check before the Mailchimp campaign goes to your subscribers.

How do I preview a Mailchimp email in Gmail and Outlook?

Create a MailSlurp device preview, copy its render address, and use Mailchimp's Send test action to deliver the finished email to that address. MailSlurp then captures the selected Gmail, Outlook, Apple Mail, Yahoo, iPhone, iPad, Android, and desktop results for review. Follow the Mailchimp device preview guide.

Can I preview a Mailchimp email on iPhone, iPad, and Android?

Yes. MailSlurp supports native iOS Mail, Gmail iOS, Outlook iOS, iPadOS Mail, Gmail Android, and Outlook Android targets, with light and dark mode variants for each supported client. See all device preview documentation.

Does this test the email Mailchimp actually delivered?

Yes. Mailchimp sends the test message to a MailSlurp render address. The preview run uses the received email, so the result includes the HTML, hosted images, tracked links, footer, and other content present in that test send.

Can I test Mailchimp inbox placement too?

Yes. Start a separate MailSlurp inbox placement test, tag its current Gmail and Outlook test addresses in Mailchimp, keep the exact marker in the campaign, and see where each message landed. Follow the Mailchimp inbox placement guide.

When should I rerun a Mailchimp device preview?

Rerun the preview after changing images, copy, layout, links, tracking, merge logic, footer content, or campaign settings. Final approval should always refer to the latest delivered test email.
