About

Professionals spend 11 hours a week on email. Most of that is reading, re-reading, and writing replies that could've taken 30 seconds. MailMates sits inside Gmail and handles the tedious parts: drafting replies, pulling out action items, summarizing threads. You get through your inbox and move on with your day.

✦ FEATURES

✅ Action item extraction
This is the one feature Gmail AI, Copilot, and every other email tool somehow doesn't have. MailMates reads your threads and pulls out tasks, deadlines, and follow-ups automatically. You stop forgetting things.

🎨 Custom instructions
Tell MailMates how you write. Set your tone, your go-to phrases, how formal you want to be. It remembers, and every draft sounds like you wrote it. Sales teams use this to keep voice consistent across reps. Non-native speakers use it to sound like they've been writing English emails for years.

✉️ AI replies, powered by GPT-5.4
Open an email, get a draft. MailMates reads the full thread, not just the last message, and runs on GPT-5.4. Most tools use older or cheaper models. The difference shows up in the first reply you send.

📋 Thread summaries
Long threads, summarized. Key points, decisions, what actually needs your attention. No more scrolling through 20 messages to figure out where things stand.

⚡ Built for Gmail
It's a Chrome extension. You install it, open Gmail, and it's there. No new app, no migration, no setup wizard. Under a minute to get going.

🔒 Privacy
Emails are processed in real time and never stored. No data retention, encrypted connections, minimal permissions. We don't keep your data because we don't need it.

✦ WHY NOT JUST USE GMAIL AI OR CHATGPT

Gmail has built-in AI now. It's fine for a basic reply. But it can't pull action items from a 15-message thread, it doesn't let you set writing instructions, and it won't keep your tone consistent across 50 outbound emails.

ChatGPT can write a great email if you copy the thread, write a prompt, wait, copy the result, switch tabs, and paste it back. That workflow falls apart after email number three.

MailMates does what neither can:
→ Extracts action items (no other tool does this)
→ Applies your writing instructions to every draft
→ Reads the full thread so you don't have to copy anything
→ One click, inside Gmail, done

✦ WHO USES MAILMATES

→ SDRs and sales teams for follow-ups, cold outreach, and keeping deals moving. Most save around 2.5 hours a day.
→ Recruiters handling candidate outreach and interview scheduling at volume
→ Founders who need fast replies without losing half the morning to email
→ Account executives keeping tone consistent across multi-thread deal conversations
→ Support teams writing accurate responses to tickets without starting from scratch
→ Freelancers sending quick replies that don't sound rushed
→ Non-native English speakers writing professional emails without second-guessing every word
