To be able to send your campaign emails through Google's SMTP server you will need to take the following steps.
1. Enable 2-step verification on your Google account.
After you have enabled 2-step verification you can then move onto step 2.
2. Create your App Password to be used in your iRefer account.
Then choose "Mail" and "Other (Custom name)" as shown below.
You can name it "iRefer".
Then copy and paste the password shown in this popup...
into the password field in your iRefer email settings page as shown below.
The details you need are:
From Email: Customers will see this email address and can reply back to it.
SMTP Username: This should be your Gmail email address.
Password: This is the password you just copied from step 2 above.
Encryption Type: ssl (all lower case).
You can now send yourself a test email.
A green tick will appear next to the Send button to show that your settings are correct and a test email would have been sent to your email address entered above.
If you see a red error message, please contact us through the in-app chat so that we can help complete your setup.
3. Allow less secure apps
If after completing the above 2 steps and your getting the following error message:
Expected response code 250 but got code "535", with message "535-5.7.8 Username and Password not accepted."
You will need to allow less secure apps to access your account.
Please refer to the link below for additional information:
Allow or disallow less secure apps to access accounts
After these settings have been set, the change may not reflected immediately as it may take time for the change to propagate across Google’s internal systems.
Changes can take up to 24 hours and a warning message indicating the expected delay will usually be displayed on the page. This is to allow the changes to fully update in Google Server.
4. Allow per-user outbound gateways
This fourth option may not be necessary, but if after completing steps one to three you are still not able to connect your SMTP, please try the following.
