How would you describe the primary audience of your product?

What's the story behind your product?

Mailerio's answer:

Mailerio is built by a couple who launched their first SaaS, Ajelix, in 2022. Over the years, they struggled with email deliverability: emails landed in spam, bounce rates exceeded thresholds, customers couldn't receive confirmation emails, and it hurt their business. So, they built an email validation tool for internal use that solved the issue, achieving an average open rate of 65% and reducing their bounce rate to 0.2%. That’s when they realized that if they had this problem, others likely did too, so they launched Mailerio for public access.
