Our blog shares expert insights on email security, DMARC configuration, and deliverability optimization.
The Return-Path is not the address your users see, but it still plays a critical role in email authentication. Learn how the SMTP envelope, SPF, bounces, and DMARC alignment fit together.
OVH has a built-in DMARC generator, but it doesn't support all DMARC tags. Here's how to add a proper DMARC TXT record in OVH's DNS zone, why you should skip their wizard, and how to actually monitor what happens next.
GoDaddy hosts your domain but doesn't create SPF records for you. Here's how to add SPF and configure it alongside DMARC in the GoDaddy DNS interface, with exact steps and common pitfalls to avoid.
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.
Microsoft 365 doesn't enable DMARC by default. Here's how to configure SPF, DKIM, and DMARC properly for your custom domain, avoid common pitfalls, and actually monitor what's happening.
GoDaddy hosts millions of domains but doesn't set up DMARC for you. Here's exactly how to add your DMARC record in the GoDaddy DNS interface, with screenshots-free clarity.
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.
Forum threads keep repeating the same confusion: "SPF and DKIM pass, so why does DMARC fail?" The missing mental model is DMARC alignment. We explain aspf/adkim, organizational vs strict alignment, and why you likely rely on DKIM alignment more than you think.
