MailStorm

Live on Google Play — free download

Stop applying one job at a time. Send a hundred.

MailStorm turns a list of companies into a hundred personalized emails — written by you, sent from your own inbox, in the time it used to take to send one.

Most job seekers send around 100 emails to land one offer. By hand that costs you weeks. MailStorm does it in one tap.

  • You write every word — no AI inventing your story.
  • Sends from your own Gmail, Outlook, or Yahoo — never from our servers.
  • Free to download. Google sign-in only, no card required.

Four steps

From an empty list to a hundred sent emails

No setup marathon. Build your first campaign tonight and start sending before you go to bed.

  1. 1

    Collect companies

    Tap a mailto link anywhere on Android and the company lands in your list. Or import a CSV, or add them by hand.

  2. 2

    Write it once

    You write the subject and body — no AI, no canned templates. Drop in {COMPANY_NAME} and the app personalizes every single send. An optional CV file stays on your device; we never analyze it.

  3. 3

    Send from your inbox

    Connect Gmail, Outlook, or Yahoo on your device. Every email leaves from your account, so replies come straight back to you — and we never store mailbox passwords or tokens.

  4. 4

    Track and follow up

    See who was emailed, what failed, and who deserves a nudge. An activity heatmap and reminders keep warm leads warm.

Built for volume

Everything you need to apply at scale

Every feature exists for one reason: more applications out the door, with less of your evening lost to copy-paste.

  • Company lists that scale

    Group targets into focused lists. Import a CSV in seconds, or share a .mailstorm file with a friend who is hunting too.

  • One template, a hundred sends

    Write the subject and body once. Placeholders fill themselves in, so every email reads like you wrote it just for them.

  • Your inbox, your rules

    Gmail, Outlook, and Yahoo through official OAuth on your phone. We never see your password and never send on your behalf.

  • Momentum you can see

    A heatmap and daily stats show how consistently you apply — so a slow week is obvious before it becomes a slow month.

  • Never let a lead go cold

    Schedule a follow-up per company and get reminded on the day it actually matters.

  • Sync without the spreadsheet

    Sign in with Google and your lists, templates, and history follow you to any device.

Straight answers

Frequently asked questions

Privacy, providers, pricing — the things people actually ask before installing.

No. Emails are sent through your own Gmail, Outlook, or Yahoo account via OAuth on your device. We do not store mailbox tokens on our servers.

No. You write the subject and body yourself. The app only replaces placeholders like {COMPANY_NAME} for each company.

After Google Sign-In we store your profile, company lists, email templates, send status, activity counts, and follow-up reminders in MongoDB Atlas. We do not store email bodies you send or mailbox OAuth tokens.

On Android, when you tap an email link in a job app or browser, MailStorm can open and add that company to your list automatically.

MailStorm is free to download. The app may show ads (Google AdMob). Premium features may be added later.

Gmail, Microsoft Outlook, and Yahoo. Connect in app settings using official OAuth (or a Yahoo app password).
