Labs
Try new features before they're available to everyone.
Labs has the features we're still shaping. Switch one on for yourself in Account settings → Labs, use it in the app, your tests and your agents, and tell us what to change. When it's ready, it's on for everyone.

In Labs now
Two features to try.
Marketing and offer emails
Test what your app sends after sign-up. The Offers and Marketing areas, coupons at checkout, one offer per person, unsubscribing that sticks, consent and the marketing rules where each persona lives, and a welcome series in order and on time.
Spam score and attachment checks
A spam score out of 10 for every email, from the markers spam filters weigh, and a check for attachments inboxes block, in your checks, run reports and Reports.
How it works
On in a click, everywhere you work.
Open Labs
In the app, choose Account settings → Labs, or Labs from the help menu.
Switch a feature on
It's on for you straight away, in the app and the Chrome extension.
Your tests and agents follow
API keys and connected agents act as the person who made them, so they follow your switches too.
Switch it off any time
Its results are still worked out for every email, so switching it on again shows them for mail that already came.
What to expect
New, but not careless.

Then it's for everyone
When a feature is ready, it's on for everyone, its switch goes, and the changelog says so.
FAQ
Questions
Does switching on a Labs feature change my existing tests?
It can. Its checks start judging your emails, and your API keys and agents follow your switches, so a test that checks every email may fail on, say, a spam score of 5 or more. Switch it on when you're ready to look at what it finds.
Can I switch a feature on for my whole team?
Not yet. Each person switches features on for themselves, and each API key follows the person who made it.
Is my data kept differently while a feature is in Labs?
No. Labs features keep their records with the test address they belong to and delete them with it, as everything else does. The privacy policy covers them.
How do I tell you what to change?
Use Request a feature from the help menu in the app. It goes straight to us.
