It’s been a long time coming, and it started with a problem we didn’t even realize was costing us users. When we launched Ajelix (our first SaaS), we grew to 280K users without a marketing budget. But somewhere along the way, we noticed a silent growth killer: important emails, onboarding sequences, password resets, feature updates, were either bouncing, landing in spam, or disappearing entirely. For a bootstrapped SaaS, every single user matters. Losing them because they never saw our email was unacceptable. We dug deeper and found three truths: - Poor list hygiene kills deliverability. A few bad addresses can tank your sender reputation. - Bounces are not just “bad emails.” They’re warning signs of expired lists, spam traps, or infrastructure issues. - Disposable emails, fake accounts that sign up for freemium, hurt sender reputation That’s when Mailerio was born. Mailerio is a real-time email validation and list cleaning tool designed for SaaS teams, marketers, and product owners who need their emails to actually land where they’re supposed to. With Mailerio, you can: - Validate emails in bulk before sending - Integrate with your forms, CRM, or tools to validate emails instantly, no more fake signups or bad data slipping through. - Keep your sender reputation healthy and reach inbox Why this matters: - Protect your sender's reputation. Once damaged, it’s painfully slow to rebuild. - Recover lost revenue. If your onboarding or transactional emails don’t arrive, you’re leaving money on the table. - Scale without fear. Whether you’re sending to 500 or 500,000 people, you’ll know your list is clean. We built Mailerio because we needed it, and now we’re making it available to others before they lose users the way we almost did. Thank you for checking out our launch. I’d love to hear your experiences. Have you ever lost users or revenue due to email deliverability issues?

Big congrats to the Mailerio team! I know the founder, and this product came straight from a real pain they faced when building their first SaaS. It’s one of those problems you don’t really think about until it starts slowing everything down and eating up time and money. I’m super excited to see it out in the world.

Thank you,@victoria_rudi! You have been one of the biggest moral supporters throughout the journey. Email deliverability is usually just an afterthought, and that can seriously hurt business operations.
