Mailbird aims to make your professional endeavours easier by integrating a variety of intuitive functions into one friendly email interface – organize, search and find information with a click of a button. One important feature we have integrated is the undisclosed recipients email feature.

Sending mass email requires a few points of etiquette one being to keep email addresses private. There are a number of reasons why employees prefer to keep their email IDs private. Sending emails to undisclosed recipients ensures that you can do so in a professional manner.

The Benefits

The best way to do send an email to multiple people is to use an undisclosed recipients feature that can be integrated into Gmail or Outlook with Mailbird.

Some main benefits of sending email to undisclosed recipients are:


Concealing email addresses is a thoughtful and professional way of sending mass emails. This protects the privacy of your recipients’ responses too and ensures that other people don’t get a build up of email responses stemmed from replies to your mass email that does not concern anyone but the original sender.

Reduce junk email

Sending email to undisclosed recipients helps to ensure that people actually get your email and that it isn’t filtered out as chain emails to the junk folder.

Spam protection

Truthfully, when you send mass emails with exposed email addresses, it subjects other people to spammers, malware and viruses. Furthermore, it makes it easier for spammers get a hold of information, in extreme cases cause a breach in security through hacking.

Send personalized email 

Instead of seeing a list of emails, names can show up in place or a general title can be given such as “To the Content Department.” This allows you to send email to multiple parties with none of them knowing the other recipients.
