B2B data provider · California business contacts
California Email List
A California email list, also called a California email database or California business mailing list, is a B2B file of named contacts at companies in California (CA), from founders and presidents to finance managers, producers and software developers: each record gives a business email address, a phone number where one is on file, and the contact’s job title, company, industry, company size and city. Blue Mail Media holds 2.1M+ California business contacts; the full set is re-verified every 90 days and your selection is checked again just before it ships. You can buy a one-time file or license the database for ongoing access, narrowed by more than 70 filters such as industry, job title, company size and city.
Firms that sell to companies across California can use the California email list to put their offer in front of the people who work there.

What is the California Email List?

The California Business Email List holds 2,164,234 business contacts at California-based companies. Each entry gives the contact’s name, work email, job title, industry, company size and revenue, and a phone number where one is on file.
Searching for a CA email list or a CA email database leads to the same file: CA here stands for California, the US state. Blue Mail Media builds each order to the filters you choose, so you receive the companies and roles your campaign needs rather than a fixed package.

Testimonials
Trusted by Leading Companies
in USA, Canada, Australia, UK and more
We are always looking for new clients in the financial sector. We have found Blue Mail to be the most effective route for contacting the decision makers we need to reach. I would recommend them strongly.
Mike McGovernFounderWe faced a difficult recruit requiring us to identify physicians with specific rare disease experience. We found the contact list to the complete, timely and easy to work from. 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.
Emme PMarketing ManagerAbout this page
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 before it is sent.
- Where the data comes from
- Compiled from public registers, corporate filings, B2B directories, industry events and opt-in channels.
- Compliance, United States
- CAN-SPAM needs no prior consent for business-to-business email, but it does need accurate headers, a real postal address and a working opt out.
- Privacy laws
- GDPR covers people in the EU and UK, and CCPA covers California residents; both give people rights over their data. Blue Mail Media supplies the data; the sending decisions stay with you.
- Figures on this page
- The hero’s 2.1M+ is the 2,164,234 California business contacts in the What-is section, rounded down. A data consultant can give the count for your own filters.
- Who this page is for
- Companies that sell to California businesses rather than to consumers. For CPAs, real estate agents, restaurants, healthcare, Canada or the whole US, the pages linked near the top fit better.
Frequently Asked Questions
Yes, in the US. What you send is governed by the federal CAN-SPAM Act. It does not require prior consent for B2B email, but it makes no exception for business email, so each message needs accurate sender details, an honest subject line, a clear ad notice, your physical postal address and an opt-out you honor within 10 business days.
Yes. The CCPA exemption for business-to-business data expired on December 31, 2022, so the law now covers business contacts too. A California professional on your list can ask what you hold about them, ask you to correct or delete it, and opt out of its sale. If your company meets the CCPA revenue or data-volume thresholds, you have to honor those requests.
Yes. The CA email list, CA email database and CA mailing list sold here cover companies in California, the US state, not Canada and not chartered accountants. For Canadian companies, the Canada card near the top of the page links to the Blue Mail Media Canada list.
Not all of it. Blue Mail Media builds it from a mix of sources: corporate filings, public registers, B2B directories, industry events and other public records, with opt-in channels among them. US law under CAN-SPAM does not require opt-in for B2B email.
Not with named contacts and work emails. State business records and free directories list California companies, but rarely the person or their work address. Blue Mail Media can send free sample data so you can test the records first.
Both options exist. Buy a one-time file, or take a database license with ongoing access and refreshes. The price depends on how many records you need, how narrow your filters are and which fields you want; send your selection through the quote form for a price.
Every 90 days, plus one more check on your file just before delivery, so what you receive was verified for your order and not only at the last refresh.
At least 95% of the contact data you buy is valid. Blue Mail Media re-verifies the California business email list every 90 days and checks your file again before delivery. If more than 5% of the email addresses or phone numbers you buy bounce or fail, Blue Mail Media replaces the failed contacts free of charge.
Yes. Filter by city to keep only Los Angeles or San Diego contacts, or pick Berkeley, Sherman Oaks or San Clemente, then add industry and job title. County and ZIP code selections go through a data consultant.
Yes. Use the employee size and company revenue filters, for example companies with 1 to 10 or 11 to 50 employees, and combine them with industry and city.
3 to 5 business days from your order, including a final check of the records you picked.
Build it or buy it. Building means collecting company names from state business records, directories and company websites, then finding and checking each contact’s email yourself. Buying gets you named contacts across an industry or city at once, and Blue Mail Media re-verifies its California data every 90 days and again before delivery.
Ask a data consultant before you plan a mail-out. Every record has a business email address and, where one is on file, a phone number; the consultant will tell you whether postal addresses can be added.
Name, job title and work email of the contact, a phone number where one is on file, and the company’s name, website, industry, employee size and revenue, matching the sample table’s columns.
Yes. Blue Mail Media’s CPA, real estate agent, restaurant and healthcare lists can each be narrowed to California, and the cards near the top of the page link to them. This page covers the rest of California’s industries and roles.
Send the California industries, job titles, cities and number of records you need through the quote form, call 1-888-494-0588 or email sales@bluemailmedia.com, and a data consultant will get back to you with a quote.
