USE CASE:
Cybersecurity companies and the deliverability problem
The job on this page is deliverability for cybersecurity companies, with the options first, ours included, and the recommendation at the end. Mamba Labs writes Apify actors for work like this, and Domain Deliverability Checker is the one that reads cybersecurity companies.
What is actually going wrong
Cybersecurity companies and deliverability: the shortcuts stop working, for one specific reason. Start from this: cybersecurity companies publish less about themselves than any other category in software, on purpose, and deliverability follows. On cybersecurity companies, deliverability rarely catches this: no customer logos, no team page and no office address is a posture, not an absence of data. If you would rather try it than read about it, Domain Deliverability Checker does deliverability for cybersecurity companies today.
What is at stake
The mailbox provider will never tell you why cybersecurity companies stopped opening, which is what makes this worth instrumenting rather than debugging.
Traditional Search Tools
- Conference sponsor lists, for cybersecurity companies. Free to read, and for this category they are the closest thing to a customer list.
- MXToolbox. The tool most people already use, and it is genuinely good for one domain at a time. It is a web form, so checking 40 sending domains means 40 visits.
- Google Postmaster Tools. The only place you see what Gmail thinks of your reputation, and it is free. It covers Gmail, it needs domain verification, and it says nothing about the other half of your list.
- Your sequencer's own health check. Instantly and Smartlead both ship one. They check the domains you send from, which is the point, and they will not check a domain you have not connected yet.
- Read the DNS yourself. dig the SPF, DKIM and DMARC records for the sending domain, then check it against the public blocklists one at a time. Fifteen minutes per domain if you know what you are looking at.
