Email setup is crucial for your affiliates to register in the network and activate their accounts. This article contains the error codes you might have when setting up SMTP.
Before you begin
250 error code
“Connection error, check settings. Err=[Expected response code 250 but got code “” , with message “”]”
The default email address ([email protected]) has a limit on the number of emails. If you see the 250 error code when sending a test email, you exceeded the limit. Affise recommends you to always set up your custom email account instead of the default one.
535 error code
“Connection error, check settings. Err=[Expected response code 250 but got code “535” , with message “535-5.7.8 Username and Password not accepted. Learn more at
535 5.7.8 https://support.google.com/mail/?p=BadCredentials w22-v6sm4382727eda.34 - gsmtp
”]
If you see the 535 error code, it means two-step verification is enabled on the email account and/or access to third-party services is not allowed. The email server cannot verify the identity of the sender as legitimate.
Check the settings of your SMTP server provider to correct the setup.
220 error code
“Connection error, check settings. Err=[Expected response code 220 but got code “” , with message “”]”
If you see the 220 error code, it means failed authentication.
You should check SMTP auth related setting in your mail client application.
Error of registration
If your affiliate does not receive email notifications or sees the ''Error of registration'' message while signing up, do the following:
1. Go to Settings and make a test email for your email account:
🔎 If you don't see any error message and the test email is passed successfully, check your spam box.
Failed to authenticate to SMTP server with username
The most secure way to send mails is to use SMTP authentication. But this authentication can sometimes fail with the errors:
Err=[Failed to authenticate on SMTP server with username "[email protected]
using 3 possible authenticators]
or
Err=[Failed to authenticate on SMTP server with username "[email protected]
using 3 possible authenticators]
This error means the Less secure app access option is turned on in the email account. In the guides below, you can see how to turn this option off.
Disable Less secure app access in a Yandex account
Sign in to your Yandex account and check if there are any messages in your Outbox folder.
Enable two-step verification.
