Every Litmus plan
Litmus is sold as Validity Engage and publishes no prices: litmus.com/pricing redirects to contact sales, validity.com/pricing redirects to a lead form, and neither site shows a plan name, a rate or a trial. On 1 August 2025 it replaced the prior Basic (about $79-99/mo) and Plus (about $159-199/mo) tiers with Core at $500/mo and removed the entry-level plan; Core has since been withdrawn from the public site along with the rest of the pricing. Validity acquired Litmus in April 2025 and merged Everest deliverability into Litmus in early 2026. Real-seed inbox placement is a separate Engage capability, not part of email QA.

What the same job costs at Unspam
