Our blog shares expert insights on email security, DMARC configuration, and deliverability optimization.
The aspf tag controls how strictly DMARC checks SPF alignment. Most people leave it at the default and that's usually fine. Here's when you might want to change it.
SPF failures show up in your DMARC reports or email headers, but the reason is not always obvious. We break down the common causes of SPF failures and walk through practical troubleshooting steps.
Managing DMARC across multiple domains means logging into GoDaddy, Cloudflare, Route 53, and more. Human error is the top cause of DMARC failures. A centralized dashboard catches mistakes before they hurt deliverability.
SPF looks simple until you hit the 10 DNS lookup limit and break your email authentication. Our free SPF generator helps you build valid records, warns about lookup limits, and shows you exactly which services are consuming your budget.
Copy-pasting DMARC records from forums is how domains end up with broken email authentication. Our free DMARC generator builds valid records with the exact tags you need, explained in plain English.
Forums show the same anxiety pattern: 'I want p=reject, but I'm afraid I'll block legit mail.' The rollout is mostly about gates: inventory done, alignment fixed, SPF lookup limit avoided, and then staged enforcement.
Forwarding and discussion lists are a classic DMARC pain point: SPF usually breaks, DKIM sometimes breaks, and then users blame the receiving org. We explain why this is structural, and how ARC and SRS attempt to fix it.
A recurring forum storyline: you set up an ESP, authentication tools say it's fine, yet DMARC alignment is still broken. This usually comes down to how the ESP signs DKIM (d=), whether you're using a custom sending domain, and whether you should isolate with a sending subdomain.
