For guaranteed email delivery, Haiilo advises including Haiilo's IP addresses in your company's email Allowlists. This will ensure that all types of emails, such as invitations, password reset requests, daily digests, newsletters and more, reach your users effortlessly.

Email domain Allowlisting

Haiilo's system emails and newsletters are sent from noreply (at) haiilo.com. Allowlisting this address is often enough to ensure that the emails are allowed to be received by your company's email client. 

IP Allowlisting

In other situations, it can become necessary to allowlist specific IP addresses. Haiilo uses these IP addresses to send emails:

• For system emails (daily digest email, reset password emails, etc.): 198.2.179.61
• For newsletters emails: 159.183.104.234
