How to choose the best email verification tool
When it comes to selecting the right email verification service for your needs, there are several key criteria to consider.
Let’s break them down:
1. Accuracy
The best email verification tools have a high accuracy rate, ideally above 95%.
An email verifier with low accuracy might miss inactive or invalid email addresses or remove valid ones from your list.
Identify and remove invalid emails by using a tool with multi-layered checks.
2. Speed
For efficient campaigns, consider services that can process thousands or more verifications per hour. Launch your campaigns without unnecessary delays.
That’s a key-feature of a good email verification tool. It helps you focus on writing high-converting emails instead of waiting for the list cleaning to finish.
3. Pricing
Opt for flexible pricing models that align with your budget without compromising quality. Check which tools offer a free plan or trial to test their features before paying.
4. Integration
Don’t waste time managing multiple platforms or manually transferring data. Choose a tool that seamlessly integrates with your email marketing and CRM platforms.
5. Support
Even the best email verification tool can encounter bugs or glitches. Look for services with responsive and helpful customer support teams. Maximize the tool’s features by taking advantage of knowledgeable support teams.
6. Security
Your email list likely contains valuable customer information. Ensure that the tool you choose complies with data protection regulations in your area, like GDPR, for data security. The best tools will have clear data privacy policies highlighting how they handle and protect your email list data.

Do we really need email verification tools?
Yes!
Email verification tools are services that essentially take lists of emails and determine which addresses are deliverable and undeliverable.
For example, if you take a list of 20 email addresses and upload it into a verification tool, you’ll get a report back of how many out of those 20 were deliverable, undeliverable, and risky.
Avoiding the undeliverable and risky emails is going to ensure your domain has the best email deliverability possible aka you will avoid spam folder and your messaging will get through.
That being said, you don’t necessarily need to have a separate tool only for verifications, since this can mean an added expense in your toolkit. Find a verification tool that can do much more than that. For example, lemlist!
Frequently Asked Questions
What is an email verification tool?
In essence, an email verification tool is an app/software/tool that filters a series of email addresses and will then weed out invalid emails, leaving you with addresses that are verified and deliverable.
How can I verify an email?
You have different methods to check if someone’s email is valid.
First and foremost, use an email verification tool, where you will import a list with all of your leads’ information, whether these are email addresses, LinkedIn profiles, etc. and the tool will send you a list indicating which emails are valid and which are invalid.
You can also use a lead database (lemlist has a huge one 😉) where you can access valid and verified contact details.
Lastly, if you want to check an address or two quickly, head over to our mini-tool and get a quick verification.
How do email verification tools work?
Email verification tools take the information that has been provided and run checks concerning domain and syntax among other factors.
If they discover the addresses have no known issues, the address will be marked as valid, whereas if there are any spotted issues or spam risk it will be marked as invalid.
What is the difference between email verification and email validation?
Email verification and validation both confirm whether an email address is valid in terms of syntax, however, email verification also checks the existence of the email domain and validates that the mailbox can accept incoming emails.
Is email verification legal?
Yes. Not only is it legal, it is necessary.
In order to keep in compliance with regulations like GDPR and the CAN-SPAM Act you must confirm you are sending your emails to valid and professional email addresses and not spamming your targets.
To better comply with the regulations, don’t forget to include an opt-out or unsubscribe option to avoid any legal issues.
How important is email verification?
Email verification is a crucial step in all of your outbound activities. If you just guess on emails, knowing full well that a large percentage of those emails may bounce you will be waiting around for ages until a reply ever hits your inbox.
However, the highest risk you run is hurting your deliverability score, which will negatively impact the emails you send to actual valid email addresses.
Basically, you could get yourself stuck in spam limbo for a very long time.
