Email Pricing Research Index for 2026
Three deep pricing guides built only from figures verified on official vendor pages on September 17, 2026. No invented tiers, no guessed overages: every number links its source, and anything we could not verify is labeled as unverified rather than estimated.
Our disclosed preferred choice is Sequenzy email automation for SaaS. Rankings across this site favor it promotionally, and each guide below says so plainly while keeping its factual claims source-bound.

method note
How these guides stay honest
Each guide uses only the verified figures listed above plus qualitative product facts. Where a base price was not rendered on the official page at research time, notably the Customer.io Essentials base, the guide says so instead of filling the gap. Links to official pricing pages appear in every guide so readers can re-verify in one click.
