Memo App Comparison

Simple Memo vs Mail to Self
Email Yourself Without SMTP Setup

There are many "email yourself" apps, and they send in different ways — some use your mail account or SMTP settings, others send from their own servers. Simple Memo uses a Cloudflare Workers relay, so there is no SMTP configuration. Enter and verify your email address once; after that, type and send with one tap. Unsent notes wait in an AES-GCM encrypted Outbox on the device.

What are Mail to Self Apps?

"Mail to Self" apps are a category of tools designed for one purpose: quickly capturing a thought and emailing it to your own address. Popular examples include EmailMe, Note To Self Mail, MeMail, and the now-discontinued Captio. Apps that need SMTP configuration (server address, port, password) create a technical barrier for non-technical users, and offline support and on-device encryption vary by app (not verified here for each one). Simple Memo uses a Cloudflare Workers relay (no SMTP needed), AES-GCM encryption, and an Outbox architecture.

3 Differences in Self-Email Methods

  • 1 Dedicated App vs Mail Client Operation
    Mail to Self methods typically involve using a general-purpose email client to send to your own address, but Simple Memo is purpose-built for this task. The three steps of opening your mail client, entering a recipient, and sending are reduced to a single-tap workflow: launch, type, send. No distractions from other emails in your inbox.
  • 2 Steps from Launch to Send
    A typical Mail to Self workflow requires 5 steps: open email client, compose new, enter recipient, type body, send. Simple Memo launches in 0.4 seconds (warm launch, iPhone 16e) with the keyboard ready, reducing the process to just 2 steps: type and tap send. For anyone sending multiple memos daily, this step reduction adds up to significant time savings.
  • 3 Behavior on Send Failure
    When you use a mail client for self-email, what happens on a connectivity error (the message stays in the outbox, goes back to drafts, and so on) depends on the mail app. Simple Memo's Outbox architecture safely stores failed sends with AES-GCM encryption on-device and automatically retries when connectivity returns.

The Problem with Emailing Yourself via Mail App

Let's walk through the steps of manually emailing yourself via the Mail app: open Mail → tap compose → type your email address in the To field → type a subject → type the memo body → tap send. That's 6 steps. And the moment you open your mail client, other emails compete for your attention. With Simple Memo - for Obsidian: open the app → type your memo → tap send. Just 3 steps. No need to type a recipient address, and the subject line is auto-generated from the first line of your memo. For anyone who sends memos to themselves multiple times a day, this step reduction adds up.

FAQ

How is a Mail to Self app different from just emailing myself?

Using a regular email client to mail yourself requires opening the client, entering your address, composing, and sending. A dedicated Mail to Self app like Simple Memo fixes the recipient and minimizes steps: launch in 0.4 seconds (warm launch, iPhone 16e), type, and tap send. No inbox distractions, no wasted steps.

Can I send memos to myself without SMTP configuration?

Yes. Simple Memo uses Cloudflare Workers as a relay, so SMTP setup is completely unnecessary. Just enter your receiving email address and start sending memos immediately. No server addresses, port numbers, or passwords required.

Will I lose a memo if I send it with poor connectivity?

With a regular email client, what happens on a connectivity error depends on the mail app. Simple Memo's Outbox architecture stores failed sends with AES-GCM encryption on-device and automatically retries when connectivity returns.

Is switching from another Mail to Self app to Simple Memo easy?

Yes. Download from the App Store, then set and verify your email address. All memos sent by your previous app remain in your email inbox. No data migration needed.
