Email verification

We support uploading your email list from a CSV (comma separated value) file. You can use any spreadsheet program such as Google Sheets or MS Excel to convert the email data to CSV format.

Make sure the email addresses are in one column.

Yes. You can upload upto 1000 emails by pasting it directly. This will make cleaning your emails easier.

Turn-around time depends completely on the nature of your list, mostly the type of domains and the mail servers we reach to communicate. In general, on average it takes anywhere between 2 and 10 minutes to verify a list of 10,000 emails. But, allow a minimum of 5 minutes for even smaller sized lists, as real-time mail server communication is unpredictable.

We support additional columns in the csv file which will be retained and will be downloaded along with the results.

Most of the email hosting employs a comprehensive anti-spam mechanism including 3rd party real time blacklists (RBL) that blocks emails suspected to be spam/ unsolicited in nature. This blocking is based on both the sender reputation of your ESP (email service provider ip, domain) as well as your campaign quality including the email content, FROM email address, the links present, etc., Those blocked emails are tagged as either hard/soft by your emailing system (ESP) depending upon its own logic. So due to this even cleaned lists generate some bounces, but this does not mean those emails were invalid.

We tag emails as Deliverable only if our system gets a valid email response from the corresponding mail server, so those emails do exist and can accept emails, but accepting your campaign email depends upon your email service provider (ESP).

Catch-all mail servers respond OK for both valid and invalid addresses. So catch-all domains cannot be definitively verified.

Bouncify identifies catch-all domains using the real-time SMTP communication and tags them appropriately in the result. The catch-all identification is 100% accurate. Example for catch-all domains such as yahoo.

Our system has to do real time communication with the recipient mail server to identify if the domain is a catch-all or not. Apart from this our system processes and stores your emails, this requires storage and computing resources. We deduct credits, if the domain turns out to be a catch-all.
