Run a separate seed test across Gmail, Google Workspace, Outlook, Microsoft 365, and Yahoo to find placement problems before the full list is selected.

Start a new MailSlurp inbox placement test. Copy its marker and current Gmail, Google Workspace, Outlook, Microsoft 365, and Yahoo test addresses.

Import the current recipients into a dedicated MailerLite group, add the exact marker, and send only to that group.

Check inbox, tab, spam, and missing results, then review content and sending-domain findings before the full send.
Combine observed mailbox placement with the delivered MailerLite email, client rendering, sender authentication, and content checks so the next fix is based on evidence.

Confirm whether the campaign reaches inbox, promotions, spam, junk, or goes missing across personal and business mailboxes.

Preview the same delivered email across Gmail, Outlook, Yahoo, Apple Mail, mobile, desktop, light mode, and dark mode.
Track SPF, DKIM, DMARC, MX records, reputation signals, blocklists, and domain changes alongside each send.

Catch broken links, missing images, unsupported markup, and content warnings in the exact campaign sent for preview.
Practical answers for checking a MailerLite email before the full send.
Create a MailSlurp device preview, choose the clients and dark-mode views your audience uses, and send the finished MailerLite test email to the render address. MailSlurp then shows the delivered message in every selected client. Follow the MailerLite device preview guide.
