Sending tracking e-mails from your own domain with DKIM and SPF
To prevent your Webshipper mail notifications from being tagged as SPAM, you have to create the following two records on your own domain. This is done through your domain providers DNS administration. If you are not sure how to do this, please consult a professionel - this is out of Webshippers support scope.
You have to add Webshipper's domain customer-spf.webshipper.com in your SPF configuration.
Your configuration could look like this:
TXT "v=spf1 include:customer-spf.webshipper.com ?all"
Notice that you might have an existing SPF record - in this case you just have to add include:customer-spf.webshipper.com along with the other entries you already have.
To verify the origin of your e-mails you also have to create a DKIM record like below:
webshipper._domainkey.<your domain.tld> TXT "v=DKIM1; k=rsa;
Replace <your domain.tld> with your own domain.
