Do you still receive a lot of spam? Then follow these 5 general tips:

  1. Install Norton Security if you use an e-mail program (e.g. Outlook, Windows Mail, Apple Mail, etc.) on your mobile or computer for extra protection against spam and viruses. Norton is a chargeable option.
  2. In Proximus Webmail you can mark messages as spam. In the unwanted e-mail, tap on Hamburger menu at the top and then on Mark as spam. In future, these unwanted e-mails will be moved to the spam folder.

    Do you use another e-mail program?
  3. Never reply to spam. This only increases the chances of more spam.
  4. Don't make your e-mail address public. Never give out your e-mail address publicly on webpages or forums.

  5. Consult the tips of safeonweb, the government's website for cybersecurity.

Are your e-mails identified as spam by your e-mail recipient? Then follow these 4 general tips:

  1. Take account of the maximum number of recipients you can send e-mails to simultaneously: maximum 100 via Proximus Webmail, 100 from your own e-mail program and 10 from a non-Proximus connection.
  2. Be mindful of the content of your e-mail: avoid certain keywords (e.g. free, discount, price, win, special offer, campaign, decide now, money, etc.) and excessive use of capital letters, punctuation marks or images. Also, don't use JavaScript, Flash or colored words in your text.
  3. Don't send e-mails from an e-mail address that contains a combination of numerals and letters. By default, you'll often receive a mailbox from Proximus that is made up of such combinations, but the aim is that you create an alias.
  4. Ask the recipient to check his e-mail filters.

In that case, make sure that your newsletter contains a link that allows recipients to deregister.

Proximus automatically filters e-mails that are sent to your Proximus e-mail address. This is usually done on the basis of our e-mail standards, but also on the content, keywords or origin of e-mails. If your correspondent does not comply with these conditions, the e-mail is automatically moved to the spam folder.

If your correspondent does comply with these conditions, follow these 3 tips:

  1. Check via MX Toolbox to make sure the domain (the part that comes after the @ in the e-mail address of your correspondent) is not on a blacklist. Domains that send a lot of spam may end up on a blacklist. If your correspondent is on a blacklist, he should contact his own e-mail provider.
  2. Check to make sure you haven't set up an e-mail rule in Proximus Webmail (or in your own e-mail program) that ensures that your correspondent's e-mail is automatically moved or removed.
  3. Recommend the sender to consult our tips for outgoing e-mails above, to prevent them from being recognized as spam.
