Spf Authorizes Sparkpost

by spf-authorizes-sparkpost in Email & messaging

x402 APIPassing, checked 1 min ago

Does the domain's SPF record authorise sparkpost to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for sparkpost's include/ip mechanisms, returning yes/no, the matching mechanism and the full record. Confirms a vendor integration is wired for deliverability, or spots an unexpected sender. $0.01 per lookup.
