Klaviyo email preview questions
Send the final preview email from Klaviyo, inspect the delivered result, and keep client-specific screenshots with the launch review.
How do I send a test email in Klaviyo?
Open the email editor, click Preview, find Send a preview using a profile, enter the recipient, and click Send test. Use a MailSlurp render address as the recipient when you want the delivered message captured across multiple clients and devices. Follow the illustrated Klaviyo guide.
Can I preview a Klaviyo email in Gmail and Outlook?
Yes. Send the Klaviyo test email to a MailSlurp render address and choose the Gmail, Outlook, Apple Mail, iPhone, iPad, Android, desktop, light-mode, and dark-mode targets that matter to your audience.
Is Klaviyo Inbox testing the same as sending a preview email?
No. Klaviyo exposes Inbox testing as a separate paid-account workflow. A preview email uses Klaviyo's test-recipient field. MailSlurp can receive that delivered preview email and keep the selected cross-client screenshots in one render result.
Does MailSlurp preview the email Klaviyo actually sent?
Yes. The preview run starts from the received Klaviyo test message, so the result includes the HTML, hosted images, links, footer, and campaign content present in that delivered email.
When should I rerun a Klaviyo email preview?
Rerun it after changing copy, images, product blocks, personalization, layout, links, tracking, footer content, or campaign settings. Final approval should always refer to the latest delivered version.
