Postmark
the longest message history in the category and a price cut that made it competitive again — until you reach a hundred thousand.
the retention and reliability pick, dramatically better value at 10,000 emails than it was a year ago — and quietly the most expensive place on this page to send 100,000.
the august 2025 restructure is real and large: the pro plan covering 10,000 emails now costs $16.50 against $60.50 before, with basic at $15 for the same volume minus inbound processing. any comparison still quoting the old number is describing a different product.
retention is where it wins outright. 45 days of history as standard, extendable to a full year for $5 a month, against one day at mailgun's basic and three at sendgrid's essentials. for anyone doing customer support against email delivery, that difference is worth more than the price gap.
the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
