01
I'm considering using your email validation service but I'm concerned about the privacy of my data
02
Is there any risk that our IPs and domains will get blacklisted when using your service?
All processing is completed on our servers, so your IP addresses and domains are not affected in any way by the DeBounce service. There is absolutely no risk of your IPs and domains becoming blacklisted .
03
A valid email address just bounced. How did this happen?
DeBounce only determines if the recipient address exists. It does not test the anti-spam policies employed by the receiving mail server, as no mail is actually sent.
Make sure that your mail server’s DNS data contains valid MX, PTR, and SPF records. You should also check that the sender’s address exists and that mail to this address is accepted by your server.
Additionally, your mail server needs to have a good reputation in order to send email reliably. Cleaning your email lists before you start a new email marketing campaign helps a lot.
04
What is the maximum upload file size or maximum allowed number of emails per list?
The maximum number of emails per list is 200,000. If your list is larger, please reduce its size.
05
Do I need to install any software to use DeBounce?
No, you don’t. From the moment you upload your email lists, DeBounce will take care of the entire process. Once you’ve set up an account with us, you can upload your lists directly from your browser.
06
How often should I verify my emails?
Large lists should be checked once every two weeks, at the very least. Smaller sized lists can be checked on a monthly basis.
07
How important is it to have clean email lists?
Very important! Clean email lists ensure that your email marketing strategy doesn’t go to waste. If you send out your next campaign to unverified and outdated email addresses, you’ll find that you’ll have a very low conversion rate, as well as unreliable data. With a clean list, however, you’ll only be distributing your email to fully verified addresses, allowing you to communicate directly with your core customers and shape your email marketing efforts around them.
08
How does the email verification process work?
Our algorithms have been specially designed to utilize tools such as Domain Validation, Syntax Verifier, Spam-Trap Removal, and Email De-duplication tools. These are used to clean, verify and sort your lists. We also check the validity of MX records, as well as carry out Bounce Processing.
09
What is your accuracy rate?
Our service is 97.5% accurate, offering you the best-of-breed standard for measuring verifications. We are endorsed by thousands of satisfied customers.

Does DeBounce send out any e-mail messages while validating?
No, it doesn’t. DeBounce employs DNS and SMTP protocol functionalities to perform email address validations, and always avoids sending any email messages to external mail exchangers for delivery.

5 concurrent calls are the maximum you can perform while using the API endpoint. DeBounce API is not built to perform many or bulk validations.

04
I get a "No Access-Control-Allow-Origin" error on JavaScript calls. What do I do?
In order to allow your website to connect to the API, you need to add your website domain to the allowed CORS domains. To do so, open your API on the dashboard, click on “Set CORS Domains” and add your website address to create permissions.
05
Does DeBounce store emails that are called from the API?
DeBounce really cares about data protection and user privacy, so never stores any emails that are called from API.
06
Does deduplication feature works for the API?
No. Since we do not store the email addresses you validate using the API, the deduplication feature does not work for the API.

On every call, you will receive an update of your remaining credits on API response. Moreover, there is a separate API to view the remaining credits on your DeBounce account. See APIs documentation here.
