Impressionwise Email Verification and Spam Trap Removal

Documentation


Frequently Asked Questions

General

Are you able to verify and clean all types of emails?

Yes, we process emails from around the world and for all types of emails, including B2B, B2C, and top level domains like Yahoo, Hotmail, Gmail and AOL.

Can you automate my account?

Yes, as long as you have sufficient credits available on your account you can clean files (or use the API) on your own at any time!

Do I have to buy a credits package or can I just pay for a single file?

You do not have to purchase a credits package, you can simply pay for the exact number of emails in your file if you prefer. However, since we offer volume discounts it is often a better deal to purchase a credits package. In addition, threats are always moving and changing so having extra credits left on your account can be useful for future recleans!

What is included with the complimentary evaluation?

Our complimentary evaluation is an opportunity to clean a file of up to 100k emails and view a summary report of our findings before you spend any money. The actual results files are not part of the complimentary evaluation, but are available for purchase if desired.

How do I sign up for an account?

Our sign-up process is easy, simply click here where we will request your company name, billing address, phone, contact name and contact email. We will create an account for you and send a login to our portal where you can make payment, view credits, and upload/download files. Once payment has been received, you can start cleaning!

What does the service cost?

Please see our pricing page for information about the costs of our service, or feel free to contact us for a quote or additional pricing details.

Do you have an API?

Yes, we offer access at no extra charge to our real-time, HTTP-based API.

Do you have a service to remove only threats?

Please contact us if you wish to discuss removing threats from your list without the verification component.

Data Transfer

How can I send my data to Impressionwise?

We offer multiple methods of data transfer, including FTP, API, and our client web portal.

Can I have other columns with information in the file I upload?

Yes, files with other information are fine as long as the emails are all in the same column and are not in more than one column. When we provide you with the results, that extra information will remain intact.

Accepted File Types

Currently we accept any form of delineated file txt, csv, zip or rar extensions. If you need assistance with more exotic delimiter formatting, please reach out to our support team.

Cleansing Process

Can you automate my account?

Yes, as long as you have sufficient credits available on your account you can clean files (or use the API) on your own at any time!

How will I know when my file is done cleaning?

Our system will send you an email when the file is complete, letting you know that the results are available for download.

Why doesn't the portal show the amount I was invoiced?

For convenience, we offer the ability to make payments within our portal. We can send out invoices if you would like one, but it is not required so the portal will not show any specific amount due. You simply enter the amount you want to pay and it will email a receipt once the process is complete!

Do my results files stay available in my portal account/on my FTP forever?

No! It is very important to download your results promptly and save them elsewhere because our system will automatically delete all files from your account and FTP after 7-10 days.

Can I use credits for both file submissions and API calls?

Yes! One credit cleans one email address, whether it is in a file or via API.

Does a list cleaning last forever?

Absolutely not! Depending on the list source and quality, the recommended cleaning intervals can vary. However, in general it is important to be aware that threats are always moving and changing, so cleaning data one time will not protect you forever.

Accounting

Can you provide an invoice for our company records?

Yes of course, once you make your payment we will e-mail a receipt but are happy to also issue an invoice upon request.

How do I know when my credits are running low?

Our system can notify you when credits are running low via email. We also have an option for weekly credit balance updates via email, and you can purchase additional credits at any time.

What methods of payment do you accept?

For your convenience, we accept all major credit cards as well as PayPal, bank wires, and ACH transfers.

Data Protection and Usage

Do you keep, sell or share my data?

No we do not. We archive client files and results for 7-10 days for your convenience, but it is automatically deleted after this and you are welcome to delete it sooner if you wish.

For additional guidance or any questions you may have, please contact us.
