Click the "Remove File" button, and then click the "Back" button to return to the upload screen.

Depending on the composition and size of the data file, validation can take up to 48 hours.
You will receive an email when your job has finished processing. It will include instructions for logging in and downloading your file(s). This email will be sent to the address associated with your current login.

Your results file and reports will remain available for review or download within your Order History page for 90 days from job completion.

NOTE: We recommend re-validating all email databases no less than every 90 days. It is best to use the most recent version of your file when updating the validation.

If you need more time to complete processing, your session will remain active for up to 24 hours from the session start time.
For the best delivery results, we recommend mailing “V” email addresses first. When looking to retain more email addresses in your database, consider adding “C” and “U” emails. This decision should be made with consideration to the sender threshold designated by your ESP.

3 ArticlesAPI

The AccuValid Web Service API is a RESTful web service providing real-time validation of email addresses. Responses are formatted as JSON-encoded strings.
How email validation works:
  • Verify Syntax is valid, while j~sm is not
  • Verify DNS — "Will the host ev en accept email?"
  • Remove Problem Emails — Identify all known "spam traps," "honeypots," and "screamers"
  • Communicate — Converse with all domains, ISP, and mail servers
  • Return — Receive verified and transmission-ready email addresses in real-time.
Your AccuData account management team will deliver your secret token when setting up your API test account.
Please contact your AccuData account management team to establish your API test account and API key.

5 ArticlesList Upload & Codes

Upload as many files as you need! Each list will be validated separately and returned with a main job name and in numerical order with result codes appended to each respective file.
There is a 52 MB limit at this time. If your file exceeds 1mm records we recommend you split the file into multiple files. You can also send larger files to your sales team for offline processing.

After an email address has been analyzed, AccuValid appends a result code that will appear on the output file you receive.

The codes that are appended to your list provide comprehensive yet understandable insight about each email address. Use this to make informed decisions about deploying to the respective addresses.

(C) Email address domain verified, appears to be an accept-all domain

No, if you do not wish to have duplicate email addresses validated, please dedupe your file before uploading.

Don’t worry, it is normal for status to be delayed at 99% as AccuValid diligently works on validating the last few email addresses on your file that may have been temporarily deferred.
