Sometimes email notifications and broadcasts may be blocked by the recipient's mail server. This can sometimes happen when a Sender address is added to the notification settings. Adding a sender address is optional for notifications but currently required for broadcasts.
When a sender address is added, the 'from' and 'sender' address no longer match because the 'from' address for notification emails in Award Force is firstname.lastname@example.org. Mail servers will sometimes reject emails where the from and sender address do not match since this is a tactic used by spammers which is known as spoofing.
If you want to add a sender address to your notifications then we also recommend adding a DNS record to your domain settings to prevent mail servers from blocking these emails. To do this you'll need to sign into the account where your domain is registered and add the following SPF TXT record (or ask your domain registrar to add it for you).
v=spf1 include:mg.awardsplatform.com ~all
If there are already SPF records for your domain then you can add the Award Force record to the existing record as follows:
v=spf1 include:aspmx.googlemail.com include:mail.zendesk.com include:stspg-customer.com include:mg.awardsplatform.com ~all
Adding an SPF record will not only improve mail delivery of messages sent from your Award Force account, it will also help prevent spammers from fraudulently using your domain to send spam.
