Last verified 2026-11-01. 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 monthly prices of $25 and $62.50 recorded in an earlier version of this record 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. This note predates 3 corrections to the plans above, the earliest from 2026-09-11; the table holds the corrected figures.See the corrections.

A new dated entry is stamped here each time the price moves — the record builds itself.
From 2026-10-16 our record reflects a correction we published, not a vendor price move, so earlier figures are not compared with it.
Tracked since June 2026. No change record has cleared two sources yet, so nothing is published on the wire.
Corrections to this record
Changes we made to our own record of Mailosaur, newest first: a figure read again on the vendor's page, a plan it no longer lists, a note. None of them is a price change by Mailosaur. Every correction on the site is in the corrections log.
-
Core. Price corrected from $50 to $62.50 (month, billed monthly). This row was last read on 2026-09-02. The record had held $50, the annual-billed rate, and noted that no monthly-billing figure was published: the default Annual billing side reads Core From $50 per month, billed annually, and with the Monthly control clicked Core reads From $62.50 per month. The annual discount is set to this plan's own saving of 20%, which matches the page's SAVE 20%. The page reads: "Core POPULAR Collaborative email testing that scales with your automation. From $62.50 per month Sign up". Read in a browser on 2026-09-27.
-
Personal. Correction 2026-09-11: the recorded monthly price was moved from $20 to $25. The plan's own note calls $20 the annual-billed rate ($240 a year) and names $25 as the month-to-month price. The monthly price holds the month-to-month price and the annual discount (20%) holds the saving separately, so the row was offering 20% off a figure that already had it — $16.00, which this vendor does not charge. The discount is unchanged; only the basis of the price is corrected. Both figures come from the note as it stood.
-
Core. Correction 2026-09-11: the annual discount of 20% was removed from "Core". The recorded $50/mo is this plan's own note's $600 yearly total over 12 months, so the saving is already inside the figure, while the page prints the percentage as a further discount off the same row — offering a reader $40.00/mo. Removed rather than moved: no rate above it is named anywhere in the note. The note still describes the term in full. No price changed.

This standing as a plaque
Mailosaur currently holds a gold deskmark here — Rank 2 of 6 · Email Testing. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm, which never reads commission data. We never ask anyone to show it, and its link carries rel="nofollow".
The image is drawn from our live data, so it follows the standing rather than freezing it: if Mailosaur moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
