Email deliverability, explained plainly
What happens to an address before your email reaches it: why some bounce, what a catch-all domain hides, how to clean a list before a send, and how to compare verification tools.
Why emails bounce, and what it costs
Hard bounces, soft bounces, what each one costs your sender reputation and your sending account, and the habits that keep your bounce rate low.
How to clean an email list
A practical method for cleaning an email list before a send: gather it, drop what you already know, verify every address, sort by recommendation, decide on the doubtful ones, and send in stages.
Catch-all domains: what they are
What a catch-all domain is, why the mail server's answer cannot confirm a mailbox behind one, what PricklyMails returns instead, and what to do with those addresses.
ZeroBounce alternative: comparison
PricklyMails and ZeroBounce compared on verifiable points: pricing model, price per 1,000 addresses, free tier, credit expiry, unknown results, catch-all handling, data retention and hosting, API, and MCP.
What dead email addresses really cost
Most email tools stop billing an address once it bounces. The real cost is elsewhere: a suspended account, a tier paid until renewal, and your sender reputation.
