Read from the source, not self-reported
Every number on this page can be traced to a page we crawled or a posting we read. Full methodology →
- Website codeScripts, tags and embeds found on the company's own pages in our crawl of 41.5M sites. A tool counts once per company.
- DNS recordsSPF includes, DKIM selectors, MX and CNAME records of the company's domain that point at vsl mailsafe or another vendor. Swept in cycles; dedicated mail-provider and hosting facets open once coverage passes 80% per country.
- Job postingsRead hourly from the applicant tracking systems behind company career sites. A tool counts when the employer's own text names it as the team's system; candidate wish-lists and apply boilerplate are excluded. Confidence low, medium or high per company.
- Sending infrastructureCold-e-mail sending domains are look-alike domains on a provider's infrastructure (DNS records, certificate logs) that redirect to the company. Absence is not evidence: only companies with a found sending domain are counted.
- CompaniesCountry, size and industry come from the company profile we build from its website; headcount from LinkedIn where known, otherwise estimated. Job boards, portals and aggregators are kept out of lists.
vsl mailsafe data: questions
How many companies use vsl mailsafe?
141 as of 5 November 2026: 141 carry vsl mailsafe on their website or in their DNS records and 0 name it in their own job postings; 0 show up in both. We keep the two counts apart because they measure different things.
What does "website or DNS" mean?
Our crawler finds vsl mailsafe's scripts, embeds and tags on the company's own pages, and our DNS sweep reads the domain's mail and hosting records (SPF includes, DKIM selectors, MX, CNAMEs) that point at vsl mailsafe. Either one puts the company in the footprint. The sweep is still running, so this number grows week by week.
Why is the job-posting number so much smaller?
A posting only names a tool when the team that will use it is hiring and chooses to say so. That makes it a smaller but stronger signal: it tells you which team runs vsl mailsafe, with a quote and a date. The footprint tells you reach.
How fresh is this?
Career sites are read hourly, websites are re-crawled on a rolling schedule and DNS is re-swept in cycles. The date at the top is when these counts were computed.
Can I get the list?
Yes. The first 20 are on this page; the full 141 with verified e-mails and a weekly feed of new vsl mailsafe users is in the product. Counting is free.
