Validity acquired Litmus, killed the $99 Basic plan, and reset the floor to $500/mo (Core: 5 users, 2,000 previews). If you were on Basic, you got an eviction notice. Frame previews your email across the inboxes that matter, flags every CSS break per client, and answers the one thing Litmus never did — will it actually land?
Free to start · no signup to try · honest about what it testsNo signup. Paste your HTML and watch it render across Apple Mail, Gmail and Outlook — with a plain-English list of everything that breaks per client.
And then the part Litmus never had: a deliverability verdict. Frame is built by a deliverability company, so it tells you whether your email will reach the inbox — not just how it looks once it gets there.
