Provenance: Re-fetched mailosaur.com/pricing on 2026-06-18: the ONLY published prices are the annual-billing rates of $20/mo (Personal) and $50/mo (Core), each marked 'Save 20%' vs monthly. The monthly-billing rate is NOT published on the page. The draft's monthlyUsd values of $25 and $62.50 were fabricated 'monthly equivalents' and are corrected to the actual published $20/$50 annual-billing rates. Enterprise is contact-sales. 14-day free trial; no forever-free tier.
