When you are sending emails to your customers or suppliers from Briox, and you are using your company email address as a sender, it is important that the email does not end up in spam at the receiver's end.
All the email communication sent from Briox originates from Briox controlled servers and Sendgrid.com, and depending on the receiving party, it might be categorized as spam because of mechanism called SPF (Sender Policy Framework).
Sender Policy Framework (SPF) is an email authentication method designed to detect forged sender addresses in emails (email spoofing), a technique often used in phishing and email spam.
SPF allows the receiver to check that an email claiming to come from a specific domain comes from an IP address authorized by that domain's administrators. The list of authorized sending hosts and IP addresses for a domain is published in the DNS records for that domain.
If your company's emails sent via Briox are ending up in spam, this requires technical changes to your company's domain DNS records.
If you are not familiar with these terms, you may want to contact your service provider for your company's hosting for your domain, so they can help you to set it up for you. Or if you are running your hosting yourself, and have access to DNS records, following changes should be made to allow Briox to send your email under your own domain name, and prevent the emails ending up in spam:
Following servers are in use for each country, and the below TXT record line can be modified accordingly:
Finland: 126.96.36.199 - o4.email.briox.fi
Germany: 188.8.131.52 - o3.email.briox.de
UK: 184.108.40.206 - o2.email.briox.uk
Estonia: 220.127.116.11 - o5.email.briox.ee
Add the following TXT record to your DNS records (For Finland):
IN TXT ”v=spf1 ip4:18.104.22.168 a mx -all”
Please note that DNS propagation can take up to 24 hours globally (or sometimes even longer, depending on the set TTL), so the change is not immediate.
Additionally, if should you encounter any further problems with spam filters at your customer's side, you may want to add also sengdrid.net to your DNS records, with similar TXT input:
v=spf1 include:sendgrid.net ~all

Also, you may want to confirm that briox.fi and sendgrid.net are whitelisted at the receivers end and in their email system / spam filter lists.
