ClickSend SPF Record
If you're having issues with email delivery, ask who ever manages your domain settings, to add an SPF record.
I don't have a SPF record
If you don't have a SPF record, add a TXT record to your domain with the content:
v=spf1 include:online-send.com -all
I already have a SPF record
No problem. You simply need to add our SPF inclusion into your existing record.
For example, say your existing record looks like this:
v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com -all
You would just need to add the ClickSend lookup at the end of the string, before the *all mechanism, like so:
v=spf1 a mx include:_spf.google.com include:spf.protection.outlook.com include:online-send.com -all
