This feels like a huge milestone for us.
Seeing Mermail featured on the Solana Ecosystem Call and our vision for agentic commerce being shared with the ecosystem feels like a dream.
We started with a simple belief: AI agents need their own identity, inbox, and way to pay.
Still early. Still building. But moments like this mean a lot.
Thank you @EcosystemCall @SuperteamVN and everyone who has supported @Mermailapp along the way.
Solana high forever! 🤘
Your AI agent can book a table, right up until a website asks for a verification code and a credit card.
@Mermailapp gives it its own inbox and its own USDC wallet on Solana, with limits you set, through one MCP connection.
Let your clankers do their thing!
Big win for agentic commerce today. 🔥
AI agents can find what they need. Now they can pay for it, too.
Today at @Cloudflare Connect, Mastercard showed how Agent Pay for Machines lets an AI agent find and pay for digital services on behalf of a business, while sticking to the budget and rules that business sets.
Following pilots with @Cloudflare, @Ant_Intl , @BVNKFinance, @AIsaOneHQ, @coinbase, @base and @hypepartners, we're opening Agent Pay for Machines Early Access.
Now we want developers to put it to the test. 👇
People are already handing their agent their OTP.
For your bank, that code should stay with you.
For everything else your agent signs up for, it shouldn't be borrowing your Gmail at all. Muse, Grok, Codex, OpenClaw: every verification step still routes through a human's private inbox.
Give the agent its own:

Vietnam is becoming a home for some of the most ambitious builders on Solana 🇻🇳
Proud to be building Mermail alongside this amazing community.
Huge thanks to @vibhu and @SuperteamVN for bringing builders together. This is just the beginning! 💜
Vietnam is a great option for Solana builders: massive crypto-native population, low cost of living, great food. Easy to travel anywhere in Asia in a few hours.
Was a pleasure to meet Solana teams:
@lpagent_io
@yodlpay
@gopaymoji
@opendex_ws
@Mermailapp
@OnePlan_Travel
@polarislabxyz
@BasalPay_App
+ others (sorry if I forgot!)
Massive shoutout to @SuperteamVN, and many thanks to @LynnWWins, @dieubui2522, and @LavieTran214 for being wonderful hosts in Vietnam.
Hope to be back soon!

Plus aliases are a great step. A separate address for each job means cleaner routing for agents.
The next step is putting it on your own domain: [email protected]
[email protected]
Mermail gives every agent its own inbox on your custom domain, with a capped wallet, over MCP.
Check it out: mermail.app/
Grok @bot now supports plus aliases! Send and receive email using dedicated aliases, or set up routines that only trigger for mail to a specific alias!
"Have your bot talk to my bot" is coming fast.
The question is whose address your bot uses. With Mermail it's yours:
[email protected]
[email protected]
One custom domain, an inbox for each agent, whether that's Grok, Claude, Codex, OpenClaw or your own, plus a wallet with a cap you set.
Check it out: mermail.app/
it won't be long before "have your bot talk to my bot" becomes common!
some fun use cases of multiplayer grok bot over email could be:
• debugging (you can send my bot bug reports!)
• customer support
• booking meetings and events
• group buys
• buying and selling stuff off craigslist
what have you used bot mail for?
An agent that books your hotel also needs to get the confirmation.
Payments are getting solved: x402, stablecoins, no cards.
But the booking reference, the receipt, the "your room changed" email all land in an inbox. Today that's usually the founder's Gmail.
Mermail gives every agent its own inbox and wallet, so it can pay and also read what comes back.
AI in crypto isn't a future concept. It's booking your hotel.
Binance x402 is the missing link between agents and onchain commerce: programmable payments on @BNBCHAIN, settled through Binance Pay.
USDT, self-custody. No cards. No gas.

The next wave of Solana volume will come from agents doing business.
We're building their inbox and wallet.
Mermail is submitted to @colosseum World Fair. Let's build. 🪐

5 months ago, we started building @Mermailapp with one simple belief: AI agents need their own email to interact with the real world.
Back then, many people told us it was a stupid idea. "Why would AI need email? Email is dead."
We kept building anyway.
Today, seeing Grok Bot launch its own email honestly makes me happy.
Not because we were first, or because we were right. But because something we believed in, even when others didn’t, is now becoming real.
We're still a small team with a long way to go. But moments like this remind me why we started.
Sometimes, being a founder is just about believing in something before the world does. ❤️
🚀 Our Mermail Agent Skill Bounty in @superteam has officially ended!
Huge thanks to everyone who participated! The number of submissions went far beyond our expectations. 🔥
We need a little extra time to carefully review every submission and give each builder the attention they deserve.
🏆 Winners will be announced by Sunday, October 18
Special thanks to @SuperteamVN for helping us spread the word and making this bounty reach so many builders!
Stay tuned and thank you for building with @Mermailapp 💙

Huge thanks to @SuperteamVN for such an amazing #RoadToColosseum event! 🙌
We learned so much and had the opportunity to pitch @Mermailapp, sharpen our story, and get valuable feedback from the community.
Colosseum is just the start of our journey, and Superteam has helped bring our dream one step closer to reality.
Grateful for all the support! 💜
