Our research shows that the most common mistake users make while sending an ecard is a typo error in the email address.
We have developed sophisticated programs at the server end which checks the email address and lets you know if our postmaster feels that there could be a possible mistake in the email address you have typed.
This feature triggers an alert message when someone types an email address which is not valid.
For example: if someone types email@example.com instead of firstname.lastname@example.org then an alert message pops up saying "Did you mean email@example.com ", 'Yes or No' . On clicking 'YES' our program automatically rectifies the email address but on clicking 'NO' the email address is accepted as it is.
NOTE: DO NOT PUT SPACES BEFORE OR AFTER THE EMAIL ADDRESS OTHERWISE IT WILL BE TREATED AS INVALID.
We're working to improve this feature and if you find something which is valid, and is being reported as invalid, please do shoot us an email and we'll surely get it rectified.
