Email security tools are designed to protect your organisation from spam, phishing and malicious emails. Occasionally, this can mean legitimate emails sent from marketing platforms are filtered or blocked, particularly test emails and automated notifications.

To help make sure emails sent from Force24 arrive where you expect them to, we recommend asking your technical or IT team to allowlist our sending IP addresses and their associated sending email addresses. We also recommend allowlisting your own email sending subdomains that you use with Force24. This article explains which IP addresses and sending addresses to allowlist, and how to identify your own sending subdomains.

When do I need to allowlist?

You may need to allowlist Force24 sending IPs and email addresses if:

  • Test emails are not arriving in your inbox.
  • Automated notifications, such as form fill confirmations, are not arriving.
  • Reply notifications are not being received.

Allowlisting helps your email security system recognise these messages as trusted and deliver them correctly.

Which Force24 IPs and sending addresses should I allowlist?

Ask your technical or IT team to allowlist the following IP addresses and their associated sending addresses:

  • 84.18.201.167 is used for test emails sent from the platform.
  • 156.70.88.25 and no-reply@data-crypt.com are used for platform notifications, such as form fill confirmations and account confirmation emails.
  • 192.174.92.230 and no-reply@replies.force24.co.uk are used for standard campaign reply notifications.

Why should I allowlist my own sending subdomains?

Your Force24 campaigns are sent using your own email sending subdomain or subdomains. For example, if your organisation's website is yoursite.com, you might send emails from marketing.yoursite.com.

We recommend asking your technical or IT team to allowlist these sending subdomains as well as the Force24 IP addresses and sending addresses above. This is particularly important if you send campaigns to colleagues or other people within your organisation, as your internal email security system may otherwise filter or block them.
