Email List Services to Target the right Decision Makers

For organisations that are very serious about data privacy, and consent through double opt-ins, our b2b email lists are made just for you!

List of Email Addresses for clean and accurate data

When it comes to building a b2b email list for prospecting and finding the right decision-makers in your target industry, you need 100% clean and accurate data. Without this you will have a lot of bounced emails, along with a low open rate and a high unsubscribe rate. The only way to combat this problem is through clean data.

Clean data involves the right approach to sourcing contact details and then verifying them by keeping them refreshed and updated in real time. Ascentrik Research follows this twofold process with every project we undertake.

Why you need Ascentrik’s Custom B2B Mailing Lists

Highest conversion rate with our targeted list of email addresses!

We give you the freshest and most accurate b2b mailing lists of decision-makers and companies to target, from authentic, trusted sources. We also validate and update your existing b2b email list, if it has incorrect and out-of-date information. This helps you increase conversion rates on your marketing and sales campaigns.

0 bounce rate on your email campaigns!

We do not store data. Our b2b email lists are freshly sourced for each client. Data replacement guarantee ensures 100% ROI. Automation + Human Verification allows us to keep data fresh in real time.

From cold calls to warm leads!

We give you single and double opt-in data for consent based marketing. You can ensure that the people you are targeting have opted in to receive marketing or sales messaging from you.

Hire a team of researchers rather than downloading a b2b email list

Automated software cannot target niche industries and job functions, but manual research by experts can. Since we function as data partners, our list of email addresses are tailor made for each client. These b2b email lists are unique and not belonging to commonly demanded industries, shared by multiple competitors.

Enrich your list of email addresses

We always run the sourced email address through multi-step email verification processes to validate its accuracy. This keeps them up-to-date in real time.

Customisation in your list of email addresses

We give you the date and time of the last update, contact replacement guarantee, details about a company’s revenue, market share and decision-makers, market intelligence and sales triggers or buying signals

CRM Integration

We give you your data in any format you need. Your list of email addresses can directly be integrated into your CRM system, with our custom API.

GDPR compliant business profiles with highest privacy standards

We comply with all data privacy norms. We do not store our list of email addresses, but delete them after the final submission to the client. Every b2b mailing list is freshly built and made-to-order, to fulfil the unique specifications of each new client.

We build B2B Email Lists with custom data attributes

To build a custom b2b email list, you don’t need just a list of email addresses and phone numbers. Your email database needs to be populated with contact, company, and firmographic details, to give you a complete picture of your leads. This allows you to segment your data to identify ideal prospects and reach out to them in a more personalised way.

Customise your b2b mailing list by:

Profile Data



Social Media

Personal profile data and demographic data:
First Name, Last Name, Job Title, Seniority Level, Gender, Age, Phone Number(s), Email Address, Linkedin Profile url, Location- city, state, country

Social Media data:
This data shows the interactions between your prospect and your company. It can show if they previously downloaded something from you, liked your post on social media, or the amount of time spent browsing your website. It can also be used to retarget those contacts who could have opened an email or clicked on your ad but did not act further on it.

We can also research sectors that are highly specialised and niche.

Email Finder Tools and Email List Builder Tools

Email finder or email list builder tools help you find email addresses, direct phone numbers, company names, social media profiles, company revenue and a lot more contact and company information. Their algorithm indexes a huge number of web pages to source information, and builds and stores extensive databases. These tools help you build a lead list for marketing, sales, and business development, using a browser extension, API or web interface.

If you want to evaluate various email finder software platforms, their pros and cons, and also discover ways to overcome the drawbacks of such software tools, this is the best place for you.

While they can be incredibly useful, you’re not guaranteed to get a successful result every time you use it. The free searches are limiting and the paid options can end up being quite expensive, especially if you don’t get the addresses you’re looking for.

Our b2b email list research is more effective than email finder tools

The main problem with sales intelligence tools is data inaccuracy, because tools run on automated software processes. Secondly, building a database of contacts from niche industries and job roles, and updating them in real time is practically impossible. The solution lies in doing away with pre-built databases that rely solely on software automation. Today companies that function as data partners have found a way to circumvent the problem of outdated databases by using a combination of automated processes along with human research and validation.

We charge only for successful contacts, and in case a prospect has switched jobs we give you a replacement contact immediately. We build your b2b email list from the ground up, through custom research methods. Data is never stored in databases for multiple users. The list of email addresses and phone numbers are manually validated through phone research as well as email verification tools. Consent is obtained through single and double opt-ins.

Clients have full control over their data. They can be sure the prospect they are targeting wants to receive their marketing and sales messages. They are also assured that their data is unique from that of the competition.

Frequently Asked Questions

What is contained in Ascentrik’s email list services?

Our b2b mailing list is generally a database of individual contacts with many data points that can be used for various sales and marketing activities. The database can also include phone numbers and other company details, as well as sales triggers and competitive intelligence. 

How are Ascentrik’s list of email addresses sourced?

We collect data directly through interaction with C-level executives at Fortune 500 companies. We also use web based resources like business directories, industry commerce sites, country departmental sources, company annual reports, market reports, SEC filings, form 990, capital and private market data, magazines, publications and journals, trade shows, conferences etc. 

How do you ensure your b2b mailing list is legal?

GDPR and other country specific compliances are required to be in place. Legality has more to do with how email addresses are used. For example, emails should always offer ways to opt out of the email database. 

Are email list services expensive?

Email list services that are research based, and come with single and double opt-ins, may seem to be expensive, but are more profitable in the long run. Your list will be free from stale data, and since you have the consent of your target audience, you are more likely to get a response to your marketing outreach. 

Can I buy a list of email addresses by industry and/or by zip code?

Yes, Ascentrik offers location criteria like city and postal address that allows you to source leads based on their zip code. 

Is it better to get a list of email addresses through custom research services or download the email list through a lead generation tool?

In cases where organisations need custom company and contact data lists, partnering with data researchers is the best option. It guarantees customisation, accuracy and exclusivity. You will have GDPR compliant and SLA guaranteed data, along with single and double opt-in consent. Your CRM data will always be refreshed in real time. We even tell you the date and time your data was last updated.
