How to Improve Inbox Placement Using Brevo Tools
Email deliverability is one of the most misunderstood topics in digital marketing. You can have beautiful templates, powerful automation, and high-quality content — but none of it matters if your emails don’t reach the inbox. Brevo gives you several tools that directly support better inbox placement, reputation protection, and consistent results. In this guide, you'll learn how inboxing works, which factors matter most, and how to use Brevo tools to improve your reputation throughout 2026.
Why Deliverability Matters More Than Any Other Email Metric
Your open rates, click-through rates, and conversions all depend on a single factor: inbox placement. If your emails land in spam or promotional tabs, performance instantly drops.
Good deliverability protects your:
- sender reputation
- domain trust level
- IP score and historical performance
- user engagement signals
- future inbox placement stability
Improving deliverability means every email campaign becomes more powerful — even without changing content.
The Core Factors That Determine Inbox Placement (Brevo-Compatible)
Authentication (SPF, DKIM, DMARC)
Mailbox providers must trust your domain. Authentication is the first and most important step.
Sender Reputation
Reputation is based on engagement, spam complaints, and historical behavior.
List Quality
Outdated or low-quality contacts are the fastest way to damage inbox placement.
Engagement Signals
Opens, clicks, replies, and forwarding all boost trust.
Sending Patterns
Consistency matters. Sudden spikes hurt your score.
Content & Technical Setup
Spam-safe formatting and clean HTML reduce risk.
The Brevo Tools That Directly Improve Inbox Placement
1. Domain Authentication Dashboard
This shows the exact SPF, DKIM, and DMARC records you must add for your domain.
2. Dedicated IP (Optional for advanced users)
Gives you complete control over your sending reputation.
3. Email Preview & Spam Testing
Ensures messages are lightweight, optimized, and spam-safe.
4. Engagement Monitoring Reports
Helps identify unhealthy contacts before they damage your reputation.
5. Blocklist Monitoring
Alerts you if your domain or IP appears on any blocklist.
6. Warm-Up Sending Recommendations
Guides you through safe sending volume for new domains in 2026.
How to Set Up Authentication for Better Inboxing
Authentication acts like a passport for your domain. Without it, mailbox providers cannot trust your messages.
SPF (Sender Policy Framework)
Allows Brevo to send emails on behalf of your domain.
DKIM (DomainKeys Identified Mail)
Signs your email with an encrypted signature proving you are the legitimate sender.
DMARC
Protects your domain from spoofing and phishing.
Once these three are connected, your inbox placement improves instantly.
Warm-Up Strategy for New Domains (2026 Ready)
New domains cannot send large campaigns immediately. Mailbox providers treat them with caution until they establish trust. A safe warm-up pattern looks like this:
- Day 1–3 → 25–50 emails to engaged contacts
- Day 4–7 → 100–200 emails
- Week 2 → 400–600 emails
- Week 3 → 800–1500 emails
- Week 4 → scale gradually to full volume
Brevo’s deliverability team recommends slow, stable growth for best results.
Content Rules That Improve Inbox Placement
Even the best deliverability setup can be ruined by spam-risky content. Follow these guidelines:
- Use clean HTML (Brevo already optimizes this)
- Avoid aggressive words or high-pressure tone
- Keep image-to-text ratio balanced
- Use clear CTAs and structured content
- Avoid large attachments
The cleaner the email, the better the inbox placement.
List Quality & Hygiene (The Foundation of Inboxing)
Mailbox providers judge your sender reputation based on how contacts interact with your emails. The more unengaged contacts you have, the worse your inbox placement becomes.
How to clean your list using Brevo tools:
- Filter contacts by “no opens in last 60 days”
- Move them to a re-engagement segment
- Remove contacts who do not interact
- Suppress invalid or bouncing emails
List hygiene is one of the fastest ways to improve inbox placement.
How Engagement Affects Inbox Placement
Mailbox providers label you as a “good sender” only when subscribers interact positively with your emails. Engagement signals include:
- Opens (positive signal)
- Clicks (strong positive signal)
- Replies (very strong signal)
- Marking email as “important”
- Moving email from spam → inbox
Brevo helps track these signals using engagement score and segment filters.
How to Use Brevo Workflows to Improve Deliverability Automatically
- Tag engaged contacts after they click emails.
- Send re-engagement sequences to inactive users.
- Automatically remove hard bounces.
- Suppress risky segments before sending campaigns.
- Use automation to update “cold” tags to avoid sending to unhealthy contacts.
Deliverability improves when your list stays clean without manual work.
Common Inboxing Mistakes Beginners Make
- Sending to cold contacts without cleaning the list
- Skipping domain authentication
- Using too many images in emails
- Sending long campaigns before domain warm-up
- Ignoring bounce rate and complaint rate
