Data checked Oct 14, 2026 against the vendors' own pages. How we verify
Customer.io's cheapest paid plan costs $100 billed monthly (Essentials) or $1,000 per month billed annually (Premium). We found 25 tools in its market that cost less, compared on the same billing basis.
15 are cheaper billed monthly, 7 are cheaper billed annually, 3 have a free plan (Customer.io has none).
The largest saving on a paid plan is EmailOctopus: $9 a month billed annually on Pro, $991 (99%) less than Customer.io's $1,000.
Some plans are priced per user or per account and others per workspace, so the entry price is not always the price for your team: check the plan limits before switching.
No vendor here states that it lacks a feature Customer.io has. Below, each tool lists the features and numbers it publishes; vendors rarely state what they do not offer, so a feature that is not listed is unknown, not missing.

How we picked
- Pool: tools in the same market as the tool on this page (they list its primary category, and their own primary category is one it lists).
- Like for like: a tool's cheapest paid plan billed monthly is compared with the cheapest plan billed monthly; if that is not cheaper, its price per month billed annually is compared with the annual price. Monthly and annual prices are never mixed in one comparison.
- A free plan counts as cheaper only when the tool on this page has no free plan. Usage-priced and "contact sales" plans are left out.
- Saving = the reference price on the same basis minus the alternative's price, per month; the percentage is rounded. Entry plans differ in seats, accounts and limits, so the saving is for the entry plan, not your team.
- Sorted by price per month, then name. The page is built only when the tool has a verified paid price and at least 3 tools qualify.
Every value is read from the vendor's own pages (or GitHub for licences and stars) and shown with the date we checked it. A value we could not verify is shown as a dash, never estimated, and never read as a “no”. We did not test these tools hands-on unless a listing says so. Methodology
