New Deliverability Tools: Domain Health, DMARC & Blocklist Monitoring

Kevin Scotton May 4, 2026

The best email in the world does nothing if it lands in spam. Today we're shipping a dedicated Deliverability area that takes the guesswork out of inbox placement — and makes sure your emails actually get seen.

Your Deliverability, Graded 🎯

Open the new Deliverability dashboard and you'll get an at-a-glance letter grade for your sending setup, along with exactly what's helping or hurting you. No more wondering why opens are low or whether your domain is set up correctly.

Automatic Authentication Checks ✅

We continuously check the records that mailbox providers use to trust your mail:

  • SPF — Is your sending domain authorized?
  • DKIM — Are your messages cryptographically signed?
  • DMARC — Do you have a policy that protects your domain from spoofing?
  • MX and DNS — Are your records configured correctly?

Each check is clearly labeled OK, warning, or critical, with plain-English guidance on how to fix anything that's off. Getting authenticated — the single biggest lever for deliverability — is now something you can actually see and act on.

Blocklist Monitoring 🚫

We keep an eye on the major blocklists and alert you if your sending domain or IP shows up on one. Catching a listing early is the difference between a quick fix and weeks of tanked deliverability.

Sender Reputation at a Glance 📊

Your reputation score is tracked over time, so you can see the impact of list cleaning, better segmentation, and improved engagement — and spot problems before they cost you.

Free Workspaces Land in the Inbox Too 📬

Setting up your own authenticated domain is the gold standard, but it isn't always where you start. Free workspaces now send through an automated, shared warmed sending-domain pool — professionally maintained and monitored — so your emails have a strong reputation behind them from your very first send.

Combined with our list cleaning tools, this gives you an end-to-end picture of your sender health in one place. Keep your grade high, and keep landing in the inbox.
