HubSpot email QA questions

Practical answers for checking a HubSpot email before the full send.

How do I preview a HubSpot 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 HubSpot test email to the render address. MailSlurp then shows the delivered message in every selected client. Follow the HubSpot device preview guide.

Does the HubSpot 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 HubSpot 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 HubSpot 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 HubSpot checks?

Run the checks again after changing copy, images, personalization, layout, links, tracking, sender details, footer content, audience, or campaign settings.
