Hello Product Hunt Community 👋
I'm Vinoop, Co-Founder of Mailercloud, and I'm excited to introduce Mailercloud Email API — built to help developers send both transactional and marketing emails with speed, scale, and high deliverability.
Many of our customers needed more than campaign tools — they required reliable infrastructure to send OTPs, alerts, password resets, order confirmations, and marketing communications from a single platform.
With this launch, we’re expanding Mailercloud beyond email marketing into powerful email infrastructure for growing businesses.
Key Highlights:
⚡ 1,000+ emails per second throughput
📈 99%+ deliverability performance
📊 Real-time tracking & webhooks
🔐 Secure domain authentication & inbox monitoring
We would truly appreciate your feedback and questions — especially from developers building products that depend on reliable email delivery.
Looking forward to your thoughts and discussion 🚀
Sounds very interesting! And in Gmail, do the emails go to the Inbox or the Promotions tab?
From my personal experience, there are limitations with reaching out to peoples' inboxes rather than spam when sending multiple exactly the same emails or similar. The algorithms also adapt and try to prevent such things. If I want to send for instance 30 emails to different people saying more or less the same things, what is the chance of it reaching these individuals and can this email be twisted 30 times so that it remains sort of original?
This looks brilliant. Is there a secret 'early adopter' code" that makes the second month cost a literal pound? Would love to commit long-term if I can ease into it...
Congrats! Nice expansion, moving from campaigns to infrastructure makes sense. How do you maintain 99% and deliverability at scale?
This is great, @vinoop_thayatt! Does it sort your email into folders as well? Congrats on the launch!
This sounds like a powerful tool. Since it supports sending up to 1,000 emails at once, does it also have safeguards in place to ensure deliverability and prevent messages from landing in spam or promotions?
Congrats on the launch! This looks like a solid upgrade for teams that need both marketing and transactional emails in one place 🚀
This looks super interesting - great job Vinoop and team. Keen to test Mailercloud out.
Email API adds real power to the platform💪 Congrats on the launch @vinoop_thayatt @amar_cp @shigha_tharayil 🔥🔥🔥
The move from email marketing tool to full email infrastructure is the right expansion. Teams building SaaS products don't want to stitch together separate providers for transactional and marketing emails, and the deliverability risk of doing it wrong on OTPs and password resets is too high to cut corners on.
99%+ deliverability is the number everyone claims but the real question is how it holds up on cold domains and newly authenticated sending infrastructure. How does Mailercloud handle the warm-up period for new domains, is that managed automatically or does the developer need to control it manually?
Building a SaaS platform myself right now and reliable transactional email for things like billing confirmations and auth flows is exactly the kind of infrastructure that needs to just work without babysitting. Congrats on the launch!
