⚔️ Autocatch vs Addy.io: Two Ways to Solve the “Inbox Problem”
If you’re an indie developer, you likely want one of two things: a way to stop companies from tracking you, or a way to pipe email data into your apps without managing a mail server.
Addy.io (formerly AnonAddy) and Autocatch both handle email at the MX level, but they are built for different mental models. Since it’s important to be honest—especially when comparing tools—let’s look at exactly how each one solves common tasks.
🛠️ Problem: Creating a New Alias
The “magic” of both tools is that you don’t have to go into a dashboard every time you need a new email address. However, the logic behind that magic differs.
| Feature | Autocatch | Addy.io |
|---|---|---|
| Primary Method | Passive Discovery. You give out xyz@yourdomain.com. When the mail hits our MX, we create the entry in your dashboard automatically. | Standard Aliases. You give out anything@user.addy.io. The first mail “activates” it. |
| Control | Always “Catch-all” by default. | Can toggle Catch-all ON or OFF for custom domains. |
| Pre-generation | Not usually necessary; intended for on-the-fly use. | Encouraged for shared domains (like @addy.io) via browser extension or UI. |
The Takeaway: Autocatch assumes you want everything and organizes it after the fact. Addy.io assumes you want a shield and lets you decide if the door should be wide open (catch-all) or strictly restricted to pre-made keys.
🌊 Problem: Routing the Data
Once an email hits the server, where does it go? This is where the architecture of the two products diverges.
In Addy.io: The “Forwarding Relay”
Addy is built as a highly configurable relay. You define “Recipients” (your real email addresses).
- The Workflow: You create a rule: “If mail comes to
billing@domain.com, forward it tofinance@gmail.com.” - The Focus: Keeping the “From” and “To” headers clean so you can reply anonymously. When you reply to a forwarded email, Addy intercepts it and sends it back out as the alias.
In Autocatch: The “Data Pipeline”
Autocatch is built as an ingestion engine.
- The Workflow: Beyond simple forwarding, the focus is on Webhooks. You point an alias or a domain to a URL endpoint.
- The Focus: Turning email into a
JSONpayload. Instead of just reading the mail in your inbox, you’re likely piping that data into a database, a Slack channel, or an AI prompt.
⚙️ Task Comparison: How it’s handled
| Task | Autocatch | Addy.io |
|---|---|---|
| Blocking Spam | Blackhole an alias or a specific sender with one click in the logs. 🚫 | Deactivate or “forget” an alias; sender gets a bounce or a silent drop. 🛡️ |
| Team Access | Multi-forwarding: Send one incoming mail to 5 different teammates simultaneously. 👥 | Multiple Recipients: Assign specific aliases to different “real” email addresses. |
| API/Automation | Focused on incoming data. Pipes mail bodies/attachments to your apps. 🤖 | Focused on management. Use the API to create/delete aliases programmatically. 🛠️ |
| Encryption | Standard server-side TLS. | PGP Encryption: Can encrypt mail before forwarding to your inbox. |
🏁 Final Breakdown
Both products allow you to use your own custom domains. Both products save you from the nightmare of configuring Postfix or Exim yourself.
- Autocatch is designed for the developer who sees email as input data. It’s about building workflows where email is just another triggered event.
- Addy.io is designed for the user who sees email as identity. It’s about creating a robust, multi-layered wall between your real life and the services you sign up for.
If you need a tool that handles PGP and lets you reply to emails anonymously, Addy.io has that refined. If you need a tool that turns emails into webhooks and handles team-wide routing without friction, Autocatch is built for you.
