Understanding Email Délivrabilité

Délivrabilité is the percentage of your emails that reach the inbox (not spam or promotions). It’s influenced by multiple factors.

Sender Reputation

Your réputation d’expéditeur is a score that ISPs (Gmail, Yahoo, Microsoft) assign to your sending IP addresses and domain. It’s built au fil du temps based on:

• Taux de rebond: Hard bounces (invalid addresses) hurt reputation
• Spam complaints: Recipients marking your email as spam
• Engagement: Opens, clicks, replies improve reputation
• Spam trap hits: Sending to old, invalid addresses used to identify spammers
• Sending patterns: Consistent volume vs. sudden spikes

IP Warming

Lorsque vous start with a new IP address, ISPs ne faites pas trust it. IP warming involves gradually increasing sending volume to build reputation:

Tip: Most bulk email fournisseurs handle IP warming for shared IP plans. Dedicated IPs require you to manage warming.

Authentication Protocols (SPF, DKIM, DMARC)

These protocols verify that emails are legitimately from your domain and n’ont pas been tampered with.

SPF (Sender Policy Framework)

SPF tells receiving servers which IP addresses are authorized to send email for your domain.

Example SPF record:

v=spf1 include:spf.brevo.com include:_spf.google.com ~all

This authorizes Brevo and Google to send on behalf of your domain.

DKIM (DomainKeys Identified Mail)

DKIM adds a digital signature to your emails that proves ils ontn’t been modified in transit.

Comment ça fonctionne:

1. Your email provider adds a cryptographic signature to email headers
2. The receiving server checks the signature against your domain’s public key
3. If valid, the email is authenticated

DMARC (Domain-based Message Authentication, Reporting & Conformance)

DMARC tells receiving servers what to do with emails that fail SPF or DKIM checks.

DMARC policies:

• p=none: Monitor only (report failures but deliver emails)
• p=quarantine: Send failing emails to spam
• p=reject: Block failing emails entirely

Example DMARC record:

v=DMARC1; p=quarantine; rua=mailto:[email protected]

Setting Up Authentication

Most bulk email fournisseurs guide you through authentication setup. Here’s the general process:

1. Add SPF record: Include your provider’s SPF servers in your DNS
2. Configure DKIM: Add the DKIM public key to your DNS
3. Set up DMARC: Start with p=none to monitor, then escalate to quarantine or reject
4. Verify configuration: Use tools like MXToolbox or your provider’s verification

Délivrabilité Meilleures pratiques

1. Clean your list regularly: Remove bounces, unsubscribes, and inactive abonnés
2. Use double opt-in: Verify abonnés want to receive emails
3. Maintain consistent volume: Avoid sudden spikes in sending
4. Monitor métriques: Watch taux de rebond, spam complaints, and engagement
5. Segment engaged abonnés: Send to active abonnés more frequently
6. Include clear unsubscribe: Make it easy to opt out (reduces spam complaints)
7. Avoid spam triggers: Watch for words and formatting that trigger filters
8. Authenticate your domain: Set up SPF, DKIM, and DMARC

Questions fréquemment posées

How many emails can I send with a bulk email service?

Sending limits vary by provider and plan. Free tiers typically allow 100-300 emails par jour. Paid plans range from thousands to unlimited emails par mois. Enterprise plans can handle millions of emails daily. Choose a provider based on your volume needs—most allow scaling as you grow.

Is bulk email the same as spam?

What’s the difference between shared and dedicated IP addresses?

Shared IPs are used by multiple senders—your reputation is affected by others’ behavior. Dedicated IPs are exclusively yours—you control your reputation entirely.

Can I send emails transactionnels with a bulk email service?
