Message #campaign-qa
Check whether your Mailjet campaign reaches the inbox
Send a separate test to Gmail, Outlook, and Yahoo seed inboxes to see folder placement and sending-domain findings before the production audience receives it.
01
Create a fresh seed run
Start a new MailSlurp inbox placement test. Copy its marker and current Gmail, Google Workspace, Outlook, Microsoft 365, and Yahoo test addresses.
02
Send the marked Mailjet campaign
Import the current recipients into a dedicated Mailjet contact list, add the exact marker, and send only to that list.
03
See where the campaign landed
Check inbox, tab, spam, and missing results, then review content and sending-domain findings before the full send.
See more than Mailjet's delivered status
Combine observed mailbox placement with the delivered Mailjet email, client rendering, sender authentication, and content checks so the next fix is based on evidence.
Check Mailjet inbox placement
Confirm whether the campaign reaches inbox, promotions, spam, junk, or goes missing across personal and business mailboxes.
Render on real devices
Preview the same delivered email across Gmail, Outlook, Yahoo, Apple Mail, mobile, desktop, light mode, and dark mode.
Verify sender authentication
Track SPF, DKIM, DMARC, MX records, reputation signals, blocklists, and domain changes alongside each send.
Audit links and content
Catch broken links, missing images, unsupported markup, and content warnings in the exact campaign sent for preview.
Mailjet email QA questions
Practical answers for checking a Mailjet email before the full send.
How do I preview a Mailjet email on iPhone, Gmail, and Outlook?
Create a MailSlurp device preview, choose the clients and dark-mode views your audience uses, and send the finished Mailjet test email to the render address. MailSlurp then shows the delivered message in every selected client. Follow the Mailjet device preview guide.
Does the Mailjet test use the email customers would receive?
Yes. The preview starts from the delivered test message, including its HTML, hosted images, links, footer, and campaign content.
Can I test Mailjet inbox placement as well?
Yes. Start a separate inbox placement test, use its current test addresses and exact marker, send the campaign, and check inbox, tab, spam, content, and sending-domain results in MailSlurp. Open the Mailjet inbox placement guide.
Is inbox placement the same as device rendering?
No. Device previews show how the delivered email looks. Inbox placement shows which folder receives it. Run both before an important send.
When should I rerun these Mailjet checks?
Run the checks again after changing copy, images, personalization, layout, links, tracking, sender details, footer content, audience, or campaign settings.
