Brevo Deliverability Review: How to Ensure Your Emails Reach the Inbox

Struggling to see your Brevo campaigns land in the inbox? You’re not alone. Deliverability is the single biggest factor that determines whether your carefully crafted messages generate results or disappear into the spam folder. In this review we break down the most important elements that affect Brevo deliverability, give you actionable steps to fix common problems, and share a few advanced tricks for keeping a healthy sender reputation.

Why Deliverability Matters

Even the best subject lines and copy won’t matter if the email never arrives. Poor deliverability reduces open rates, hurts conversion metrics, and can damage your domain’s reputation across all ESPs.

Key Factors That Influence Brevo Deliverability

1. Sender Authentication

• SPF – Confirms Brevo is allowed to send on behalf of your domain.
• DKIM – Adds a cryptographic signature that verifies the email hasn’t been altered.
• DMARC – Gives you control over how receivers handle failing messages.

Without all three, inbox providers treat your messages as suspicious.

2. List Hygiene

• Remove hard bounces and inactive subscribers weekly.
• Use double opt‑in to confirm engaged contacts.
• Segment inactive users and run re‑engagement campaigns before deletion.

3. Content Quality

• Avoid spammy keywords (“free”, “buy now”, excessive exclamation marks).
• Keep the text‑to‑image ratio balanced – 60% text, 40% images is a safe rule.
• Include a clear and functional unsubscribe link.

4. Sending Practices

• Warm up new IPs by gradually increasing volume (10k → 30k → 60k per day).
• Maintain a consistent sending schedule; sudden spikes raise red flags.
• Monitor bounce, complaint, and spam‑trap rates – keep each below 0.5%.

Step‑by‑Step Checklist to Boost Brevo Deliverability

1. Verify DNS Settings
   • Log into your domain registrar and add the SPF record recommended by Brevo (e.g., v=spf1 include:mail.brevo.com ~all).
   • Copy the DKIM public key into a default._domainkey.yourdomain.com TXT record.
   • Implement a DMARC policy (start with p=none and move to p=quarantine after 30 days).
2. Clean Your List
   • Export contacts, run them through a verification service, and re‑import only validated addresses.
   • Set an automation in Brevo that tags contacts who haven’t opened in the last 90 days.
3. Test Your Email
   • Use Brevo’s built‑in spam test or a third‑party tool like Mail‑Tester.
   • Check rendering on mobile and desktop – broken HTML triggers spam filters.
4. Monitor Reputation
   • Track the “Sender Score” and Brevo’s own deliverability dashboard.
   • React quickly to spikes in complaints; pause the campaign and investigate.
5. Iterate
   • Run A/B tests on subject lines and preview text to improve open rates.
   • Analyze post‑send reports and adjust segments accordingly.

Advanced Tips for Power Users

• Custom Tracking Domains – Use a branded sub‑domain for click tracking to avoid being flagged as a generic mailer.
• Domain Warm‑up Services – If you’re switching from another ESP, services like Warmup Inbox can automate safe volume ramp‑up.
• Feedback Loops (FBL) – Subscribe to ISP feedback loops (e.g., Gmail, Yahoo) through Brevo’s integrations to automatically remove complainers.

Frequently Asked Questions

What is the biggest cause of email bounces on Brevo?

Invalid or outdated email addresses. Regular verification and a strict double opt‑in process reduce hard bounces dramatically.

Do I need a dedicated IP for good deliverability?

Not initially. Shared IPs are fine for volumes under 50,000 emails/month if you maintain hygiene. Dedicated IPs become valuable when you consistently send high volumes and have a strong reputation.

How often should I review my SPF/DKIM records?

Whenever you add a new sending service or sub‑domain. A quarterly audit is a good habit.

Can I send promotional and transactional emails from the same Brevo account?

Yes, but keep them on separate sending domains or sub‑domains to protect the reputation of your primary marketing domain.

What should I do if my emails land in the spam folder?

Pause the campaign, check authentication, run a spam test, clean the list, and resend a cleaned version with a different subject line.
