The same scenarios, priced on both

One person, 12 months, cheapest billing option on each.

Scenario HideMail addy.io
12 aliases, a few newsletters a day, no custom domain $0 (free plan) $0 if your mail stays under 10MB a month; otherwise Lite, $12
40 aliases on one custom domain Premium: $35.96 ($8.99 × 4 quarters) Lite: $12 (up to 100MB of mail a month). Pro: $36 for unlimited mail
Paying monthly, no yearly commitment $4 × 12 = $48 Pro: $4 × 12 = $48. Lite is shown only with yearly billing

The same job in both: have an AI assistant create and track an alias

HideMail

  1. Connect HideMail's MCP server to Claude or another MCP client and sign in.
  2. Ask: "create an alias for the hardware store newsletter".
  3. The assistant calls create_alias with that note and gives you the address. Later, "turn off the hardware store alias" calls deactivate_alias.

addy.io

  1. Create an API key in addy.io settings.
  2. Connect a third-party tool or write a script that calls the addy.io API.
  3. Or skip the assistant: with a username subdomain, make up any address on the spot and addy.io creates it when the first email arrives.

addy.io's username subdomain makes creating aliases by hand very fast. HideMail is built for letting software do it for you.

What switching actually involves

FAQ

Is addy.io or HideMail better for a free plan?
It depends on how much mail you get. addy.io Free has unlimited aliases on your username subdomain plus 10 on shared domains, but only 10MB of forwarded mail a month and no replies. HideMail Free has 15 aliases and forwards up to 100 emails a day. If you get newsletters with images, addy.io's 10MB can run out quickly.
Which is cheaper for a paid plan?
addy.io. Its Lite plan is $12 a year billed yearly and includes a custom domain, replies from aliases and 100MB of mail a month. HideMail Premium is $35.96 a year when paid quarterly, or $4 a month. addy.io Pro is $36 a year billed yearly, or $4 a month.
Can I reply from my alias?
On addy.io Lite and Pro, yes (50 and 200 replies or sends a day). Not on addy.io Free. HideMail does not hide your address when you reply on any plan.
Does either work with AI assistants like Claude?
HideMail has an official MCP server with 17 tools for creating, listing, disabling and annotating aliases and setting up custom domains. On 2026-10-15 we found no official MCP server for addy.io. Both have a REST API.
Can I move my aliases from addy.io to HideMail?
Aliases on your own domain, yes: point the domain at HideMail and import addy.io's CSV export (Settings, Account Data). HideMail recreates each alias with its description and on/off state. Aliases on addy.io's shared domains or your addy.io username subdomain stay with addy.io.
What happens if I stop paying?
On addy.io, custom domains, extra usernames, recipients beyond one and shared-domain aliases beyond 10 are deactivated. On HideMail, existing aliases keep forwarding; you just can't create new ones over the free limit.
