Comment Set Up DKIM, SPF, and DMARC
Email authentication is essential for deliverability. SPF, DKIM, and DMARC records prove your domain owns the emails you send. Without them, ISPs are more likely to reject or mark your messages as spam.
Prérequis
Avant de commencer, assurez-vous d'avoir les éléments suivants.
- Access to your domain DNS settings
- An OutSends account with a verified sending domain
- Basic DNS configuration knowledge
Guide étape par étape
Suivez ces étapes pour configurer votre envoi.
Log into your DNS provider
Go to your domain registrar or hosting provider where you manage DNS records (Cloudflare, GoDaddy, Namecheap, etc.).
Add SPF record
Add a TXT record: v=spf1 include:_spf.outsends.com ~all. This authorizes OutSends to send on your behalf.
Add DKIM record
Add a TXT record for the DKIM selector provided by OutSends. The value is a long public key string.
Add DMARC record
Add a TXT record for _dmarc.yourdomain.com. Start with p=none to monitor, then move to p=quarantine or p=reject.
Verify in OutSends
Go to Settings > Authentication. Enter your domain and click Verify. OutSends checks all three records.
Conseils pour de meilleurs résultats
Des astuces pour tirer le meilleur parti de cette configuration.
- Commencez DMARC with p=none until you confirm emails pass SPF and DKIM
- DMARC reports help you spot unauthorized Utilisez of vos domain
- Re-verify after any DNS change — propagation can take 24-48 hours
