What is SPF and how do I set it up?
SPF is a DNS record that lists which servers are authorized to send email for your domain. You add it as a TXT record in your DNS settings.
How long does it take to improve sender reputation?
Improving sender reputation takes time. Consistent good practices over 2-4 weeks typically show measurable improvement in inbox placement.
