What’s the best way to get CTOs’ emails for ABM campaigns?

Engaging high-profile prospects in ABM campaigns can significantly increase the average deal amount and the company’s revenue. All you need is a tailored CTO email list and additional B2B data to personalise your emails – think of intent data, sales triggers, and technographics!

Create CTO email lists right in Cognism’s database.

You can gather all these data points using Cognism Prospector

  1. First, create a lead list based on your ICP (Ideal Customer Profile).
  2. Next, narrow your search to specific criteria using Cognism’s advanced filtering options.
  3. You can filter your search down depending on simple firmographics, such as industry, company name, number of employees, and revenue size, or further explore their specific SIC, ISIC, or NAICS codes.

If you want to create a super-specific ABM campaign tailored to a series of concrete events, go the extra mile by leveraging Cognism’s company event triggers to filter them down to dates and other criteria.

Once you generate CTO lead lists, export them to Salesforce, Outreach, or another tool you use. 

Choose Cognism as your new data provider. Click to book a demo.

For example, a PropTech company, Metikus, uses the Cognism platform to find the best accounts that fit their ICP. They use the hiring trigger to search for organisations hiring for relevant job titles in the last six months. This gives them a clear indication that the business is looking to scale in their space.

They also track 25 intent topics to filter their ICP and discover companies in demand for their services. They also use Cognism’s email addresses for LinkedIn paid ads.

What to do when executives ignore your emails?

An average CTO typically gets dozens of emails per day. They will likely ignore or simply miss your email.

In this case, your best bet would be directly calling the lead. As many as 57% of C-level and VP buyers across industries prefer the phone call versus directors (51%) and managers (47%). But ensure you call them using verified mobile data rather than direct dials to avoid gatekeepers and answering machines.

Cognism’s Diamond Data® is a premium cell phone numbers dataset. We manually check each mobile number to make sure you connect with the right prospect. With Diamond Data®, you can:

  • Connect with 87% of your list.

  • Increase connect rate by 3x.
  • Stay CCPA and GDPR-compliant.

We also clean the numbers from global DNC lists from the following countries: the USA, Canada, Australia, Germany, France, Spain, Ireland, Belgium, Croatia, Portugal, Sweden, and TPS/CTPS in the UK.

How to prospect to Chief Technology Officers? 

After you create a CTO contacts email list, don’t bombard them with a series of campaigns. Prospecting to them requires a strategic multi-channel approach with a lot of preliminary preparation. Use the tips below for maximum efficiency. 

1. Build trust with thought leadership

Collaborate with subject matter experts in tech to gain industry insights and deliver thought leadership content to showcase your expertise. It will boost your credibility, and technology leaders will take your advice/offers more seriously.

2. Segment your prospect list

Not every CTO on your email list will need your service. Use Cognism’s intent data to identify accounts actively searching for your product or service and target key decision-makers when they’re ready to buy. 

3. Emphasise your value proposition

Show immediate value by clearly explaining how your product or service can address the specific pain points and challenges the tech executives face in their company. 

Top tip! Focus on the long-term value rather than quick wins.

4. Leverage referrals

If you have mutual connections, ask them for a warm introduction. This will break the ice between you and the CTO on your email list. Or mention that person X recommended contacting them.

5. Demonstrate your offering’s ROI

Buying a new product or service is an investment. That said, you need to convince a company’s technology leader that your offer will likely translate into more money or other business goals.

Share success stories or case studies from clients who achieved measurable ROI with your solution. Quantify the benefits of your solution; provide numbers or percentages if possible.

How to find CTOs’ email addresses for free?

There are several tactics for finding contact information for free - using freemium plans of sales intelligence tools or doing manual research.

Some email finder tools, such as Kaspr, have freemium plans. For example, Kaspr offers unlimited B2B emails if you invite three colleagues to try their platform.

Alternatively, you can create CTOs’ lists manually. It involves analysing their LinkedIn profiles and finding the email addresses from their profiles. Some of them might include their email, contact info, or featured posts in their bios.

You can also try your luck by guessing email patterns; or are two of the most common formats.

Tips for emailing CTOs

Still not sure how to approach the CTO by email? Four actionable tips wait for you 👇

1. Customise the messaging 

Tailor your message to the CTO’s role, industry, or specific pain points that you’re aware of. Be authentic and show that you’ve done extensive research.

Examples include:

  • Refer to your prospect’s LinkedIn or X (Twitter) post as an ice-breaker.
  • Offer a case study from their industry.
  • Mention open vacancies, company news, etc.

2. Showcase social proof 

Include testimonials, case studies, and references to notable clients. This builds credibility and demonstrates your capabilities. It encourages decision-makers to consider your offering.

3. Include a professional email signature

A professional email signature is critical for anyone wanting to make a good impression, build credibility, and streamline communication. 

A good email signature should include essential contact information, such as your business address, phone number, website, and a personalised CTA. 

4. Attend offline and online industry events

CTOs often attend offline and online industry events and conferences. They’re excellent places to connect with technology executives in person and a great way to compel them to respond to your email. 

How does it work?

  • Add an event’s name to the subject line to increase the open rate.
  • See event attendees on LinkedIn and tailor your email to their interests/problems.
  • Host your own events or roundtables for CTOs to build relationships and trust.
  • Conduct industry research/a study before the event and launch an ABM campaign inviting your target audience to find key takeaways.
