Emails sent from a Hypernode are marked as spam
Troubleshooting mail from Hypernodes
Check SPF records
Check if the spf.appname.hypernode.io hostname is included in your SPF record (in the DNS zone-file). This hostname contains the IP-address of your Hypernode and the IP-addressess from Byte’s emailservers.
More information could be found here:
If the IP-address of your Hypernode is not included in this record, please send an email to firstname.lastname@example.org, so we will fix the record for you. This could happen after an up- or downgrade of the Hypernode plan.
Check if the return-path is configured correctly
If you send your emails using a PHP script, the default return-path will be email@example.com. This email address will be seen as possible spam address, so you have to change this into something else (e.g. firstname.lastname@example.org) or change it into the email address you also use in your Magento installation. We would advise you to use a valid email address which is working! If the recipient is using SAV (Sender Address Verification), and the email address is not reachable, then a spamfilter could see this as a spam message.
Check if your Hypernode is listed on a blacklist
Browse to MXToolbox and fill in the IP-address of your Hypernode to check if the IP-address is listed on a blacklist. If it is listed, you could request a delisting by yourself. Do not forget to check the reason why the IP is listed and fix it to prevent this from happening again.
If emails sent from the Hypernode are still marked as spam, please send an analysis request by email to email@example.com including a full-header of a marked message. We will investigate the reason and send you a reply with more details.
