We built an email deliverability testing tool - and it's free to use

Hey folks – just wanted to share something we built that might be useful if you're sending cold emails, newsletters, or any kind of email outreach.

We built a free tool at Inboxbooster.com that checks where your emails are actually landing (inbox vs. promotions vs. spam) for Gmail and Outlook. Our tool also provides insight into the health of your domain reputation and whether your content is triggering spam filters.

Just send one of your actual outreach emails to the list of addresses on our homepage and the resolver will let you know if your domain, content, or DNS is experiencing any issues.

If you need any help with the testing process, please don't hesitate to let me know. Happy to hear any feedback or questions!
