Mailyser
Mailyser is an email deliverability platform that lets marketers test campaigns before they go live. You send a test message to its seed accounts, and it reports whether your email would land in the inbox, spam folder, or not arrive at all across major providers like Gmail, Outlook, Yahoo, and Hotmail.
What sets it apart from traditional seed-list tools is the focus on plain-language fixes. Instead of dumping raw diagnostics, Mailyser scores your spam risk, checks DKIM, SPF, and DMARC setup, flags blocklist issues, and suggests specific changes to your content and sending infrastructure. Its Vitals dashboard consolidates Google Postmaster, Microsoft SNDS, and DMARC reporting so you can track IP reputation over time without juggling multiple consoles.
The platform targets email marketers and deliverability specialists who manage campaigns for brands and need repeatable pre-flight checks without hiring consultants. Pricing is usage-based rather than per-seat, which suits teams that run high email volume across a small group of operators.
