Comment Configurer DKIM, SPF et 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.
Se connecter à votre fournisseur DNS
Go to your domain registrar or hosting provider where you manage DNS records (Cloudflare, GoDaddy, Namecheap, etc.).
Ajouter SPF record
Add a TXT record: v=spf1 include:_spf.outsends.com ~all. This authorizes OutSends to send on your behalf.
Ajouter DKIM record
Add a TXT record for the DKIM selector provided by OutSends. The value is a long public key string.
Ajouter DMARC record
Add a TXT record for _dmarc.yourdomain.com. Commencez par p=none to monitor, then move to p=quarantine or p=reject.
Vérifier 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 votre domain
- Re-verify after any DNS change — propagation can take 24-48 hours
