How to Find Verified B2B Emails Using an Email Finder API

Ever sent a perfectly crafted email, only to have it boomerang straight back to you? 

Yeah, us too. In fact, we’d bet that a situation along those lines is exactly why you’re on this blog post, looking into email finder APIs. 

Email finder APIs are wonderful things: instead of manually hunting down contact details – or worse, relying on outdated databases – an API automates the process for you, pulling accurate, up-to-date emails straight from reliable sources. And accuracy matters: even a 1% error rate in your email list can reduce deliverability by 10%. 

Ok, ok, so they’re extremely useful. But hold up a sec. You don’t want to run off and set up the first email finder API you come across – not all are created equal. Some are slow. Some return outdated info. Others just don’t integrate well with your existing tools. That’s why businesses turn to Surfe’s email finder API – built for speed, accuracy, and flawless integration, every time. 

Today, we’re going to break down how it works and why it’s a game-changer for your prospecting workflow: 

• How an Email Finder API Works
• How to Use an Email Finder API in Your Workflow
• Why Choose Surfe’s Email Finder API Over Competitors?

Bounced emails, begone! Let’s get started.

How an Email Finder API Works

First up – how on earth does an email finder API work? 

Let’s take an example. Say the API wanted to find the email address of John Moneybags at Perfect Prospect Company. 

To make this request, either a LinkedIn URL, a combination of “firstName lastName companyName”, or a combination of “firstName lastName companyWebsite” would need to be inputted. So, in our example, that would look like John Moneybags’s LinkedIn URL, or “John Moneybags Perfect Prospect companyName” or a combination of “John MoneyBags Perfect Prospect Company Website”. 

That’s literally all it needs – next thing you know, the email finder API would come back with the requested data (so in our example’s case, “John Moneybags’s email is john.moneybags@perfectprospectcompany.com). Magic.  

How to Use an Email Finder API in Your Workflow

Ok, so you know how it works – but now you’ve got the data from the Surfe API, what do you do with it?

The short answer: it’s up to you! 

The long answer: it’s up to you, but generally speaking, APIs like this are used by developers to build custom workflows. If your workflow needs accurate B2B data (like email addresses, job titles, or phone numbers, for example) then an API can be a very, very useful addition.

Automate Outreach with Email Sequences

Let’s say you’ve got a lot – and we mean a lot – of outreach to do. You (if you’re multitalented and can sell and code at the same time) or your team (if you’re a human being like the rest of us) could write a script to power your email automation tool (like Outreach or Salesloft, for example) with data from Surfe to set up a personalized, multi-step email sequence. 

Or, perhaps you could write a script that watches for engagement on your LinkedIn posts – and when someone comments on a post, you could send that person’s LinkedIn URL to Surfe and let it hunt down their email address. From there, you could automatically send them a personalized email – all without lifting a finger or keeping a careful eye on every single LinkedIn engagement ever (because who has time to be refreshing for dopamine hits, after all? Definitely not us. Nope, absolutely not). 

Enhance Engagement with Personalization

Once you’ve got loads of lovely enriched data from the Surfe email finder API, you could use an AI-driven sales tool (think Clay or Lavender) to personalize email content based on it. 

For example, you could write an email sequence based on the pain points of people who have a certain role at a company, and then send it to them – thanks to Surfe, you know exactly what everyone’s job titles are. 

Track & Optimize Performance

Or, maybe you could integrate the Surfe email finder API with revenue intelligence platforms like Gong or Chorus to analyze engagement and call performance? From there, you could (with a helping hand from analytics tools like Google Sheets or Databox) track outreach efficiency and refine your messaging based on your results. Clever, right? 

Automate Follow-Ups & CRM Updates

We all know that follow-ups and updating your CRM aren’t the most exciting elements of a role in sales. Well, you could eliminate them entirely thanks to the email finder API – all you’d need to do would be to set up a Zapier or Make (Integromat) workflow to trigger follow-ups, and sync prospect activity across tools. 

Honestly? Those ideas are just scratching the surface. By integrating the Surfe API with your CRM, email automation, LinkedIn, and analytics tools, you can create a highly efficient, data-driven sales workflow that saves time, boosts engagement, and increases your conversion rates.

Why Choose Surfe’s Email Finder API Over Competitors?

So, we’ve run through exactly how an email finder API works, and what you could use it for (although remember, the opportunities on that front are literally endless). 

Next up, which email Finder API should you choose? 

There’s only one answer, and one answer only to that – Surfe. Here’s why: 

Speed: Fastest Enrichment in the Industry

The Surfe email finder API is really, really fast: it can enrich 1 contact per second when you’re enriching contacts in bulk. 

For context, other email finder APIs can take up to 30 seconds per contact when enriching in bulk. Now, 29 seconds difference might not sound like very much on its own – but when you’re enriching at scale, it can quickly become a pretty significant chunk of time. 

The faster you can enrich your data, the less time you’ll have to spend hanging around and waiting – which means the more time you’ll spend being productive. Win. 

Accuracy: Verified, Reliable Data

An email finder API is only as good as the data it provides. If you’re reaching out to prospects with outdated or incorrect emails, you’re potentially damaging your sender reputation and deliverability rates – which can be a big problem for someone who has to send a lot of emails for their job. Just call us Einstein. 

Surfe’s email finder API delivers an 85% global find rate, climbing to 90% in the U.S. and other key markets. Unlike many providers that pull from static, outdated databases, Surfe continuously updates its contact information, ensuring you get up-to-date, verified B2B emails every time.

Cost: Competitive Pricing Without Unnecessary Extras

Not all email finder APIs have clear pricing. Some might appear to have low base costs, only to tack on hidden fees for integrations, API calls, or extra features you’ll never use.

Surfe takes a different approach. Its API is competitively priced without forcing you to pay for unnecessary add-ons. You get what matters most – fast, accurate B2B contact data – without surprise charges creeping up on your bill. 

Depth of Data: Continually Expanding

A great email finder API will do more than surface contact details. Instead, you should look for deeper insights to make smarter outreach decisions. Surfe already provides a rich set of data points at both a people and a company level, which helps sales teams build well-informed prospect lists.

And it doesn’t stop there. In the coming months, Surfe will expand its offering to include buying signals and more detailed firmographic data. That means even more context on your prospects, so you can reach out at the right time with the right message. Sweet! 

Let’s Wrap It Up!

Chuck your boomerang away – you won’t get any emails coming back to you with the Surfe email finder API. 

We know we’ve said it already, but we’ll say it again: it’s a great choice if you’re after one that’s fast, accurate, and competitively priced. Plus, you’ll enjoy accurate data ready for you to personalize any way you like, at any time. Where do we sign up?! 

Email Finder API FAQs 

How Does an Email Finder API Work?

An email finder API automates the process of finding verified B2B emails by pulling data from multiple reliable sources. To make a request, you typically need a LinkedIn URL, a full name and company name, or a name and company website. The API then processes the request and returns an accurate, verified email address. That’s it – simple!

Why Should I Use an Email Finder API Instead of Manual Prospecting?

Manual prospecting is time-consuming, error-prone, and frustrating. Even if you manage to track down an email address, there’s no guarantee it’s still valid. An email finder API automates the process, delivering fast, accurate results without any hassle on your behalf. It continuously updates its database to make sure the emails you get are fresh and reliable. Plus, if you’re prospecting at scale, an API can process hundreds – or even thousands – of contacts in minutes. 

What Makes an Email Finder API Reliable?

Not all email finder APIs are created equal. A reliable API has a high find rate, continuously updates its data sources, and verifies emails before delivering them. Surfe’s email finder API, for example, boasts an 85% global find rate (90% in key markets) and ensures each email is accurate before returning it. Some competitors rely on outdated or incomplete databases, which is only going to lead to high bounce rates and wasted effort. If you’re using an API for sales outreach, accuracy is everything – because a bad email list can tank your deliverability and hurt your sender reputation.

Can an Email Finder API Integrate With My Existing Sales Tools?

Yes! A good email finder API should integrate seamlessly with your existing sales stack. Whether you’re using a CRM, email automation platform, or LinkedIn prospecting tools, an API should work in the background to enrich contact data and keep everything up to date. For example, Surfe’s email finder API can connect with tools like Outreach, Salesloft, Gong, and Zapier, making it easy to automate workflows, personalize outreach, and sync data across platforms without lifting a finger.

How Much Does an Email Finder API Cost?

Pricing varies depending on the provider, but beware of hidden fees. Some APIs might look like they have low base costs, only to charge extra for integrations, API calls, or unnecessary add-ons. Surfe’s email finder API keeps things simple – competitive pricing without surprise charges. You only pay for what you need: fast, accurate B2B contact data, and nothing else. If you’re serious about prospecting at scale, investing in a high-quality email finder API is worth it – especially if it helps you land more meetings and close more deals.
