Email Bounces Troubleshooting

Some sending email addresses may experience higher than expected bounce rates.

This is usually when they are generic office email addresses (eg beginning with admin@ or office@, etc).

There are 3 ways to improve the chances of email being received:

  1. Add the email address to contacts
  2. Verifying the domain name
  3. Whitelisting the sending servers

1. Add the email address to contacts

  1. This is best for individual subscribers experiencing difficulties receiving your emails.
  2. Ask these subscribers to add your sending email address to the contacts list (or address book) linked to their email browser software.
  3. Ask these subscribers to look for your emails in their JUNK, SPAM or PROMO folders and to change their status to NOT JUNK.

2. Verifying the domain name

  1. Verifying your domain name for the email address you send your Feedsy emails and is entirely optional but it can increase the chances of your emails landing in people's inboxes (and not being filtered as SPAM). For more info.
  2. If you wish to do this then please email and request us to be send some info to give to your IT person:
    1. It will be simple instructions to add a TXT record into the DNS (it's easy and will take a few minutes).

3. Whitelisting the sending servers

  1. OK, this is pretty full-on and is only very rarely needed when receivers from the same location/server cannot receive emails.
  2. This is the job for a system administrator.
  3. Below are the addresses you can whitelist if you're having trouble delivering email from Feedsy software to your own network. Depending on your situation, you can whitelist sending domains or IP addresses.
  4. Return-path sending domains
    1. Instead of whitelisting all of our sending IP addresses, you can whitelist our domains. They currently include through to
  5. Authenticated domains
    1. If you have set up authentication, you will also want to whitelist the domain you have authenticated. Subdomains can be authenticated, if your mail administrator would like to limit access further.
  6. Sending IP addresses
    1. Below are the IP ranges we use for sending email:
  7. In cases where you need to whitelist IPs to receive email from our servers, we recommend mail administrators set up custom rules within their email filtering software. To work, the rule must match both of these conditions:
    1. The email is coming from one of our IPs or sending domains ( through
    2. The email contains your domain in the "From" address.
    3. Any email that doesn't match one of these conditions can be rejected. A custom rule like this is generally an acceptable solution for security teams and mail administrators.
