Ultimately, the list allowed us to quickly fill our quota, reduce team stress and directly contributed to a successful project outcome.
ManagerU.S. Life Science Management ConsultancyAfter taking service from number of marketing list Companies I found Blue Mail Media’s offering to be far superior to any other. We bought list for one of our clients online survey campaigns. We got 20% opens and 15.5% CTR for our campaigns. We got 400 completed surveys and our client was very happy with the results.
Chris WollenChief Marketing OfficerI couldn’t be happier with the results. Statistically Blue Mail Media list achieved far greater than industry standard response rates. We initiated two distinctly different test messages to 3630 & 4762 contacts in California. Both messages had open rates between 42% and 49% with click rates above 21%.
Tony de KerfCEOAs a new A I Legal Business Solutions company we interviewed several email generating companies to provide us valid email addresses. Blue Mail Media was so helpful in describing the process getting us started with an email campaign. They strategized with us on the best firms to start with. We have since begun our campaign and Wow we found dozens of potential clients.
Tim DerricksonCEOThe Blue Mail Media list we received was excellent quality. Our outreach saw strong engagement, and we were impressed with the accuracy of the data. It made a real difference in the success of our campaign.

How often the data behind this page is refreshed, where it comes from, and the compliance position.
- Data refresh cadence
- Re-verified every 90 days, and your own file verified again on the day it is sent
- Where the data comes from
- Compiled from public registers, corporate filings, B2B directories, industry events, public sources and opt-in channels.
- Compliance position
- Under CAN-SPAM, US business-to-business email does not require prior consent, but it does require accurate headers, a real physical postal address and a working opt out. GDPR and CCPA set a different standard. Check the rules for the region you are mailing.
Frequently Asked Questions
Yes, in the United States. CAN-SPAM does not require prior consent for business-to-business email, but every message needs accurate headers, a valid physical postal address and a clear opt out that you honour. The EU and UK require a documented lawful basis instead, normally legitimate interest, and California's CCPA gives contacts rights over the data you hold.
Chief security officer. This list covers the executive who owns physical and information security. Chief sales officer is a different role and a different buyer, and it is not what this file holds. If that is the one you want, ask at quote stage and Blue Mail Media will price it against the right titles.
Yes. The file can carry the chief security officer alone, or widen to chief information security officers, VPs of security, heads of information security and security managers. Tell us which layer buys what you sell and the selection is built to it.
Every file is verified again on the day it is sent, and the database itself is re-verified every 90 days by AI and human checks. If an email hard-bounces or a phone number is wrong, we replace the contact. Blue Mail Media runs those checks against the chief security officer records before a file is released.
Three routes. Build one by hand from company websites and LinkedIn, which is slow and works for a short target list. Ask a data provider such as Blue Mail Media for a file built to your filters. Or check whether your CRM already holds the accounts and only the contacts are missing. Whichever you pick, ask when the records were last verified.
Yes. The CSO email list is built for multichannel outreach: email marketing, telephone, direct mail and social. Segment before you send, add your opt out and honour it. Blue Mail Media supplies the data compliant with GDPR, CCPA and CAN-SPAM, and the campaign itself remains yours.
Yes. The list can be cut by country, by US state and by industry, and built to order from more than 70 filters including company size and revenue. Banking, healthcare, defence and critical infrastructure carry the deepest security teams, so say which you sell into when you request a quote.
You choose the titles. A file can carry the CSO alone, or widen to CISOs, VPs of security and security managers. For the wider technology buying group, the CIO email list covers chief information officers.
Yes. Blue Mail Media supplies phone numbers alongside company name, job title, industry, company size, revenue, website and postal address, where they are available and verified. If a number turns out to be wrong or not working, we replace the contact.
Every 90 days, and again on the day your file is sent. Most list vendors do not state a refresh cycle anywhere on the page, so it is worth asking before you buy from anyone.
Yes. Blue Mail Media builds a free sample to your own filters: industry, country, US state and company size. Each record carries the same eight fields as the full file, so a sample drawn to the segment you actually sell into tells you more about fit than a generic one.
Pricing depends on how many records you need, how many filters you apply and which geographies you want, so it is quoted rather than published. Send the selection and Blue Mail Media returns a record count and a price for exactly that.
Three to five business days from the point your order is placed, which covers building the selection and the verification pass on the file before it is sent.
Build it if you are targeting tens of named accounts, because the research time per record is the same whether you need 40 or 4,000. Buy it once the companies you want outnumber the hours you have. Security leaders also change roles often enough that a list built six months ago has already decayed, so either way check the verification date.
Tell us the segment you need, covering industry, company size, country and US state, and Blue Mail Media will quote against it. You can reach the data consultants on 1-888-494-0588 or email sales@bluemailmedia.com, or use the quote form on this page.
