Back in 2010 I had an idea for a service that would allow people to easily create semi-permanent email aliases so that they could give an email address to people and websites without revealing their real email address. These aliases will continue to work indefinitely unless you choose to block them. My brother and I spent a few months building the initial version and launched the website in July 2010. For the first year we had about 50 signups per month, by 2013 this had increased to 1500 and it's currently around 3500 per month. Similarly, our revenue grew consistently but slowly - doubling…

AhaSend▲132I'm the founder of AhaSend. We've built a transactional email service specifically for developers, with a Pay-As-You-Go pricing model ($0.50 per 1,000 emails) and up to 70% volume discount for platform partners.

Hey HN, I’m a solopreneur and have been in the SaaS space for the past 3 years. My last 3 startups failed, and a common challenge in all of them was figuring out how to reach my audience. Recently I started with cold outreach (its a struggle, since I dont have much experience with marketing). I am finding leads mainly using exa.ai websets (web vector search, extremelly good for multiple use cases, recommend checking them out) and then sending them through smartlead. I ran the campaign for the past 30 days and 12-15% emails always bounced. This wasted my email credits & chances of reaching…

Hi HN – Kristyna here. I built this free, online email validator and would love to share it with you. What it checks: - Syntax – Confirms correct proper email format. - Domain & DNS – Verifies the domain exists and resolves. - MX records – Verifies the domain can receive mail. - SMTP handshake (optional) – Checks the mail server accepts the recipient (no message is sent). - Disposable domains – Flags temporary inbox providers that can hurt deliverability lists. - Common typos – Catches mistakes and suggests fixes. How it works: Paste an email > click Validate > get a clear result with…
