Five Day Money Back Guarantee Period

Email YoYo offers a 5 day money back refund for our services rendered.

Service is billed at the start of each service month (based on the day of the month you signed up for service) for the following month and we cannot give any refunds for partial month’s service.

Security and Reliability

The security and reliability of our email validation service (API and list cleaning) is our highest priority. There are times when we cannot guarantee 100% reliability. These cases are:

  • Internet congestion
  • Critical Security Updates
  • Terrorist attack
  • Acts of God
  • Virus/Worm/Denial of Service Attack

You specifically agree that Email YoYo cannot be held liable for any missing data, corrupted data, incorrect transmission of data, failure to provide service, delay of service provision or anything in any way connected to the our services in excess of the cost of service provided.

Cumulative liability of Email YoYo to a customer shall not exceed the total monthly service fee of the immediate prior one month of service.

Accuracy of Email Validation

Checking of email addresses is a complex process involving our servers communicating with external mail servers. A service of this nature cannot be 100% accurate due to factors outside of our control such as:

Email server down or not contactable
No mail servers defined for a domain
Email server busy
Mail box is full / exceeds quota
Mail sever responds with incorrect data. Specifically, mail servers that are configured to always respond that an email address exists (whether, in reality, it does or not)

Other factors that can adversely affect accuracy include non-standard mail server implementations such as:

Some mail servers are configured to report “valid” email boxes regardless of whether they exist or not. These “false positive” results may indicate a mail box is valid when, in fact, it is not.

Examples of these types of mail servers include (but not limited to) some installations Microsoft Exchange Server. We do our best to identify these types of servers with a “Blocked/rejected” status but cannot guarantee that this flag is applied in 100% of cases.

In the case of these “false positive” results, the only way of establishing a mail box validity is by sending an email to the recipient and asking them to respond.

The following web based email providers have been known to issue incorrect responses to email validation services:

AltaVista
Yahoo
Hotmail / Live / MSN

You agree and understand that our Email validation service cannot, therefore, be 100% accurate.

Some email servers and/or ISPs implement extremely aggressive anti-spam policies. These policies can prevent our service from establishing the required network connection to allow email address checking. Where possible, we mark these services with a “blocked/rejected” status but cannot guarantee this in 100% of cases.

Stated Accuracy

Even with the external factors listed above, our email validation services have been carefully engineered to deliver the best possible accuracy of any solution on the market. Therefore, we state our accuracy figures as between 93% to 97% based on a typical list of email addresses. (Updated 6/14)

In testing in June 2014, we were able to achieve our stated accuracy on a repeatable basis and using several different email lists in excess of 2,000 email addresses per list.

Transmission of Data

You agree that Email YoYo is not responsible for any unauthorized access or modification of your data stored by or transmitted via the Email validation service.

You also agree that Email YoYo is not responsible or liable for any content sent using, or received from, the Email validation service including that which may be illegal, obscene, defamatory, threatening or that may violate any trademark or copyright.
