Our Mission is to Democratize Email Validation and Data Quality

TheChecker is a technology company that makes it fast, easy, and affordable for companies at any size to improve their data quality by using email validation tools.

Sending emails is not enough.
You have to deliver.

Based on the last 100 million emails we verified in 2019, 23.51% would bounce. We make sure you reach your customers.

Avoid the ESPs blockages

A tiny ~5% bounce rate can get you blocked by the ESPs. Our single and bulk email list cleaning tool gets you protected to improve inbox deliverability and reduce bounce rate.

Protect your sender reputation

1 out of 5 emails is not delivered due to problems related to IP and domains. We run a thorough email list cleaning to remove them and protect your sender reputation.

Increase campaigns ROI

Our innovative email checker promotes superior deliverability (up to 99.9%) to the inbox, converts more sales, and increases your campaigns ROI.

US$20+ billion in sales opportunities are lost each year

According to SendGrid, about 20% of wanted emails end up never reaching their intended recipients, resulting in tens of billions of dollars in estimated revenue loss opportunities globally each year.
