What is an Email Guessing Tool?
An email guessing tool has a few different terms, including email guesser, email syntax checker, and email format checker. These tools serve the main function of predicting potential email address variations, allowing you to connect with prospects when you can’t authenticate their email address.
But there are several other email finding tools out there! To help you differentiate between them, we explain what each type of email finder tool is below:
- Email finder: Find and collect valid email addresses when you input a professional’s name, job title, company, domain, and other identifying information.
- Email extractor: Find and extract email addresses from website domains using an automated tool, saving these manual efforts.
- Email checker: Verify and validate email addresses to check the authenticity of emails, increasing your email delivery and response rate.
Common Features of an Email Guesser
The main feature of an email guessing tool is email guessing and prediction; the user inputs a first name, last name, and domain, and the tool predicts potential email address variations. These tools commonly have a number of additional features that enhance their ability to predict email addresses accurately.
Below are some of the main features email guessing tools have:
- Email guesser: Guesses potential professional and business email variations when given a first name, last name, and domain.
- Domain email pattern lookup: Guesses potential email patterns that a company will use and determines the most likely variation.
- Misspelled domain detection: Detects potentially misspelled email addresses and suggests modifications to clean up your lead lists.
- Syntax validation: Automatically detects and corrects syntax errors found in email addresses, ensuring your emails are delivered properly.
- Domain validation: Identify email addresses with inactive or invalid domains known for spam and abuse.
It’s important to note that many comprehensive email finder tools that have an email verifier do not have an email guessing tool. In most cases, any tool with an email verification tool does not use an email guesser, as it would be unnecessary if emails were validated when being collected.

The best thing about it: Find the best leads for your industry by searching social networks and enriching contact details
An email guesser will automate the process of trying all potential email variations, allowing you to attempt to connect to leads that you cannot verify. This saves your team the time to test all variations themselves, using standard business patterns to quickly generate potential variations.
The main flaw with this method is that only one of the variations will be accurate; by nature, this method has a low delivery rate. To more effectively target leads, you can use an email finder tool that finds authentic email addresses and other contact details.
