Apollo.io

Apollo is one of the best direct email list providers. In fact, it is an AI sales platform that offers relevant email lists from its database, which helps you to reach your target audience without much effort.

What else does this B2B email list provider offer?

Well, this platform claims to provide a database of over 275 million contacts, but when you log in and check the database, it feels like the number is way less than what it claims. I felt a bit off from what I expected.

Anyway, if you can ignore it, then you can use it as a go-to database for purchasing your business email lists.

Something that captivated me about this email provider tool is that it highlights buying intent and provides scores of your leads based on what you sell.

Which means you will have the edge to prioritize your leads by using filters and zeroing in on your target audiences.

On the flip side, many users complain about their complex interface and the pricing that appears to be expensive.

Not only this, some users also reported that their database often appears to be incorrect. That said, you can still go for it if you're targeting a small email list with a more scrutinized audience.

Let's check out the pricing.

Lusha is pretty good with its data coverage, as it offers substantial email lists of over 45 M+ across North America and Europe, along with GDPR-compliant contacts.

One of the unique selling features of Lusha is that it provides compliant contacts that allow you to extract email lists and reach out to your target audience without worrying about legal laws.

On top of that, it offers data based on buyer intent; with this, you can access industry-specific email lists.

It is the same as Apollo, where you can understand what your buyer is looking for and provide a solution based upon it. In turn, you will be able to save time on searching for the target audience.

The only drawback of this platform is that it offers limited coverage. Restricted to North America and Europe. This will not fit you if you're aiming for a broader audience.

That said, let's quickly jump to pricing.

Apart from this, you can explore your prospects with intent data, which helps you to find audiences who are interested in the solutions you provide.

But there is one drawback with Uplead, and that is its interface, which is quite outdated. Not only this, its pricing is also way too expensive.

Snov.io is a combination of a reliable mailing list provider and sales automation acceleration tool. It is intended to create email lists that directly connect with potential customers.

It’s a game-changer for businesses looking to reach out to a broader audience. Although it is among the best direct mailing list providers, it has not disclosed its database publicly.

What else can you get on this platform?

This is the go-to option for some looking for a platfrom to build emails from their database and reach out to them.

To find out your potential leads, you can use the filters option provided by this platform. But, it may not be that helpful with my experience.

Why? I tried to find a marketing manager list, but there wasn’t a direct filter for that. So, I had to hand-pick them, which turned out to be bit of a hassle.

On the other hand, it promises to provide 98% accurate data, which is not the same but a little less than that. Yet it is good to go

What I like the most is that it comes with HubSpot and Zapier integration to keep your CRM updated.

Also, you will get Snov.io built-in CRMs to keep maintaining your leads and measure your campaigns.

That said, let's look for pricing

Why Should You Choose a Reputable Email List Provider?

It is very important to choose a reputable B2B email list provider to avoid falling into a trap with legal issues.

Even though you chose a reliable mailing list provider, just don’t brush off the thought that everything will be sorted. No!

You have to keep in mind certain legal guidelines to make sure you are on the safe side.

Why?

Buying email lists from an untrustworthy platform or using them in the wrong way can get your domain flagged; in the worst cases, you will end up breaking the law.

Don’t worry! Follow these simple 4 steps to keep your email list safe and spam-free:

Choose a compliant platform

Whenever you buy emails for outreach, check for platforms that comply with the regional guidelines. For example, the GDPR guidelines are liable for someone who wants to perform outreach in Europe.

Always verify your email lists

Always use tools that verify your email list to avoid invalid or outdated emails. Irrelevant emails can increase the bounce rate and a rise in spam complaints, which can lead to your domain being flagged.

So, you shouldn’t skip on verifying emails before using them, even if the email list provider claims to offer highly accurate emails. This ensures compliance with anti-spam regulations

Include a clear opt-out option

You need to include an easy unsubscribe option, because GDPR and CAN-SPAM have made this option mandatory.

Know the regional laws

Don’t ignore regional laws because all regions have varied laws; for example, GDPR for Europeans, CCPA in California, and CASL in Canada.

If you're targeting a broader audience worldwide, then you must understand these laws. Plus, you need to choose an email list provider that has various compliance certificates.

What is the Cost Estimation to Buy Email Lists

So far, I've covered you with the legalities and recommended the best B2B email list provider tools.

Now, you must be wondering what is the right price to buy an email list.

According to my experience with different platforms, I found that you can buy 1000 emails along with buyer intent, costing around $20 to $30.

This means that every email should cost you not more than $30. If So, go for other platforms.

Conclusion

By now, you must have understood that it is crucial to choose a reliable mailing list provider to scale your outreach game.

It's not just about having a bunch of contact lists, but it's more about connecting with ideal prospects who are interested in your products and making sure that you're following the guidelines, too.
