If you want to add the Customerly SPF record on top of the SPF you are already using, follow the instruction below:

Let's assume you have google SPF in your TXT record: 

v=spf include:_spf.google.com ~all

What you need to do is adding the Customerly SPF in this way:

v=spf1 include:_spf.google.com include:spf.customerly.io ~all
