What’s all this then?


Hello there inquisitive + button clicker! Welcome to Addtosenders.com

Add to Senders has been put together by the charming folk over at Campaignmaster, an email marketing company in London. One day, we were looking for a helpful website that could tell us how to add email senders to our contact list. Then we discovered, there wasent one :'(

So, we took it upon ourselves to create a dedicated website where people could quickly find this information, hooray! Hopefully you’ll find your email client here, but we’re still in the process of adding more.

While you’re here, why not pop over and see us? If you’re interested in email marketing we’ve got a lot to show you!

Oh, go on then!

Barracuda Networks

The Barracuda Spam Firewall is a popular spam filtering solution. Barracuda uses several algorithms and processes to determine whether emails are spam. Occasionally, it will mark a legitimate message as spam. There are two methods to whitelist email senders so that the firewall will not quarantine future email.

Whitelist Quarantined Senders

  1. Open your email client. Barracuda should send you a summary each day listing quarantined items. Choose the most recent Barracuda email message.
  2. Locate the email that you do not want quarantined in the future. Click on the word “Whitelist,” which is in green print to the right of the email title. This will open your list in a web browser.
  3. Click the box to the left of the email address. At the top of the page, click “Whitelist.” Barracuda will not block or quarantine the sender whose email address appears on the whitelist.

Whitelist Senders and email addresses

  1. Open your web browser. Navigate to your company’s Barracuda firewall homepage.
  2. Click on the “Block/Accept” tab.
  3. Choose “Sender Domain Block/Accept.” Enter the domain name from the email address to whitelist. For example, you can enter aol.com to allow all AOL addresses. You may enter a comment to remind you why you allowed this domain. Click “Add.”
  4. Click your mouse on the “Email Sender Block/Accept” tab. Enter the email address. Include a comment. Click “Add.” In the future, Barracuda will not block emails from the email address entered.

Trend Micro

You can prevent an email message from being incorrectly moved to the Spam Mail folder within the Anti-Spam Toolbar.

The Anti-Spam Toolbar detects spam by looking for certain keywords in the email’s subject or body and matching it with the anti-spam pattern file. Occasionally, it may detect what you consider legitimate email as spam.

To prevent this from occurring you can do either of the following:

  • Add to the list of Approved Senders
  • Decrease the Spam Email Filter Strength

Note: You can also select our email and click Not Spam to report it to Trend Micro. However, this feature serves only as a reference when they develop their spam database, and it may not have an effect on how the toolbar detects spam.
