Spam Control

Spam Control

Spam emails can be very annoying and at the same time finding an important mail in spam can also be equally annoying. Our anti-spam mechanism works extensively to identify and classify the spam mail. If you still find that some of the genuine emails land in spam, you can avoid it by adding the sender email to Whitelisted emails or the entire domain to the whitelist domains, if you trust the entire domain.

On the contrary, if you find that a particular domain or email address, always sends you spam emails but are delivered to your Inbox by mistake, you can add them to blacklist. So any email from the listed domain or email address will be sent to Spam.

You can classify a domain or an email address as whitelist or blacklist based on your preference.

Steps to Add Email Address or Domain to Whitelist or Blacklist

  1. Go To Settings  » Anti-Spam Lists
  2. Click on Domains tab if you wish to add a domain to whitelist or blacklist
  3. Enter the relevant details in any one of these fields
    • Add new whitelist domain - To add the domain address specified to Whitelisted Domains
    • Add new blacklist domain - To add the domain address specified to Blacklisted Domains
  4. Click on Email Address tab if you wish to add an email address to whitelist or blacklist
    • Add new whitelist email - To add the Email address specified to Whitelisted Email
    • Add new blacklist email  - To add the Email address specified to Blacklisted Email
  5. Click the Plus sign next to the corresponding field.
  6. The given domain/email will be added in the chosen list.


  • You can use Mark As Spam for any email to quickly add a sender's email address to the blacklist.
  • You can search the existing lists by clicking on the Search sign next to the relevant list.
