“No SPF record found” means there is no v=spf1 TXT record on your domain, so receivers can’t check which servers may send your mail. Fix it by publishing one TXT record at the domain root listing your senders, ending in ~all or -all, e.g. v=spf1 include:_spf.google.com ~all.
Create a TXT record at your root domain (host @) starting with v=spf1, add an include: for each sending service, and end with ~all (soft) or -all (strict). Only one SPF record is allowed per domain.
SPF alone isn’t enough for DMARC — the SPF-authenticated domain must align with your From domain. Pair SPF with DKIM and DMARC for full protection.
