How to Check Valid Emails Using AI for Free

Introduction

In today’s digital marketing world, many freelancers work hard to collect email data for outreach campaigns. Especially in marketing and sales, freelancers often scrape or gather hundreds or even thousands of emails. However, many of these emails are fake, invalid, or inactive. When you send campaigns to fake emails, you get poor results, low open rates, and even risk damaging your sender reputation.

One common problem is that freelancers don’t know which emails are fake and which are real. As a result, they spend time and effort sending messages to useless addresses — and get little or no response.

The Problem with Paid Email Verification Tools

There are plenty of email verification software solutions available today. While they do the job, most of them are paid tools and won’t let you verify emails for free. For beginners or those working with small projects, paying for these tools might not be a practical option.

The Free AI Solution

The good news is that you can use AI tools like ChatGPT, Google Gemini, or Grok to clean your email lists — completely free.

Here’s how you can do it:

1. Go to any AI tool such as ChatGPT, Google Gemini, or Grok.

2. Paste the following prompt:

   I will provide you with a list of email addresses.  
   Your task:  
   1. Remove all emails that START with any of the following prefixes (before the '@' symbol):  
   hi@, hello@, example@, test@, testing@, demo@, demo123@, fake@, fakename@, try@, trial@, sample@, no.reply@, noreply@, abc@, xyz@, email@, emailme@, mail@, contactme@, name@, yourname@, fullname@, username@, user@, profile@, account@, guest@, visitor@, temporary@, justme@, me@, myself@, your@, you@, john@, jhon@, johndoe@, doe.john@, jd@, j.doe@, jane@, jane.doe@, j.d@, j.doe123@, abc123@, 123abc@, random@, randomname@, default@, unknown@, unnamed@, blank@, anonymous@, first@, last@, first.last@, f.lastname@, flast@, nameless@, ghost@, nobody@, nothing@, zero@, void@, empty@, john123@, jane.doe1@, user.001@, guest.2024@, abc.def@, hello.123@, hi.there@, you.are@, me.you@  
   2. Keep only the real, usable emails that do not match these patterns.  
   3. Output the cleaned list as plain text without numbering, bullet points, or explanations — just one email per line.  
   

3. Paste up to 100 emails at a time into the chat. Avoid putting more than 100 to ensure accurate results.

4. The AI will instantly filter and give you only the real, valid-looking emails.

5. Repeat the process for the next batch of 100 emails until your full list is clean.

Why This Works

AI can quickly recognize patterns in your email addresses and remove the obvious fakes. While it’s not a complete SMTP-based verification like paid tools, it’s an excellent free starting point for small campaigns and early-stage projects.
