How may I help you?

One credit equals one email validation; however, if you pick priority processing for your list, each validated email address will cost you five credits.

We only deduct credits if we can positively verify an email address for you.

Pay As You Go Plans:

• Credits on the Pay As You Go plan never expire.
• These credits can be topped up at any time.

Subscription Plans:

• Unused credits expire at the end of each month for all subscription options.

You can purchase Pay As You Go credits as well as subscribe to a subscription plan. If you have both subscription plan and Pay As You Go credits, our system will always withdraw subscription plan credits first, followed by credits from your Pay As You Go balance if necessary.

Our recommendation is to create a numbered column in your spreadsheet if the order of the emails is important to you. You can sort your rows by this column when you download your results.

You can only submit .CSV files.

Be sure to select the “Header Row” option when uploading your files if they contain a header row. Upon uploading the CSV file a screen will be displayed that lets you match the column that contains the email addresses that need to be validated.

A Catch-all email address provides domain users the option to receive all mail sent to their domain, even if they are sent to an email address that has not been set up for their domain.

When you validate an email address or a list of email addresses, all invalid email addresses are automatically updated in your personal, account-level blacklist. The next time you validate any email address, it is checked against your blacklist and if found, the verification of that email address is halted as it was found to be invalid earlier.

The blacklist feature helps you save money as repetitive validations of priorly tested and invalid email addresses are not re-validated. This helps you save on credits thereby saving you money.

Yes, indeed. You can delete individual addresses from your account level blacklist. You can also flush your entire blacklist and start it from scratch. Head over to the Blacklist Management section to manage it now.

We understand that email addresses can go from valid to invalid and invalid to valid. This can happen due to many reasons such as temporary email account suspension, a person leaving an organization or re-joining after some time, mail server issues, and many more situations. You might want to temporarily disregard the blacklist and validate an email address or a list of email addresses.

The bypass blacklist feature helps you to do just that. When you bypass the blacklist, the system does not look up your input email address/es against your account level blacklist. This bypass happens for that single transaction (single email address or list/bulk validation). Do note that in case you bypass your backlist, all verified email addresses will be chargeable. The next time you validate an email address/list of email addresses, it will be looked up against your blacklist unless you bypass it again.

Spam traps, also known as honeypots, are used to monitor and identify spam mail. Spam traps are used to attract spammers by anti-spam organisations, ISPs, and corporations.

TuxMailer email validation service removes quite a few spam traps. There is no service that can remove spam trap email addresses completely. If any service claims to do so, then get away from them, it’s mostly a cash grab. Always send emails only to valid addresses and never purchase lists. Always build your own lists through the double opt-in process.
