Time-Delay & Frequency Logic in Brevo Workflows (Complete Professional Guide)

Time-delay and frequency logic are the heartbeat of every successful automation workflow inside Brevo. You can have the perfect emails, the perfect triggers, the perfect segmentation — but if your timing is wrong, your workflow will underperform. Send too fast, and you overwhelm subscribers. Send too slow, and you lose momentum. Use the wrong delay logic, and your workflow becomes irrelevant.

This guide breaks down exactly how time-delays, frequency caps, pacing rules, wait conditions, and delivery optimization work inside Brevo. You’ll learn how to structure long workflows with perfect timing, how to avoid sending too many emails, how to optimize delivery windows, and how to sync frequency logic with user behavior.

Why Timing & Frequency Matter in Brevo Workflows

Email automation is not just about the content — it’s about the moment it arrives. When timing matches user intent, engagement skyrockets. When timing is off, even the best email gets ignored.

Correct timing improves:

• Open rates — because emails feel natural, not forced
• Click-through rates — because offers arrive at the right moment
• Conversions — because users receive CTAs when interest is highest
• Deliverability — because paced sending improves sender reputation
• List health — because you stop overwhelming inactive users

Every workflow succeeds or fails based on timing and frequency.

Types of Time-Delays in Brevo

1. Fixed Time Delay

The simplest delay type. You choose an exact amount of time to wait before the next step.

Examples:

• Wait 1 hour
• Wait 24 hours
• Wait 3 days

Fixed delays work well for welcome flows and simple nurtures.

2. Conditional Delay (Wait Until Event)

This delay waits until a specific action happens.

Examples:

• Wait until the user opens the previous email
• Wait until they click a link
• Wait until the user visits a page
• Wait until they complete a purchase

This is the most powerful delay for behavior-driven workflows.

3. Time-Window Delivery Delay

Brevo allows you to restrict email sending to specific days or hours.

Examples:

• Send only Monday to Friday
• Send only between 9am–6pm
• Do not send on weekends

This ensures emails arrive when users are most active.

4. Delay Until Specific Date

Useful for seasonal flows.

Examples:

• Wait until Black Friday
• Wait until webinar starts
• Wait until customer subscription renewal date

5. Dynamic Behavior-Based Delay

This is where Brevo adjusts timing based on user engagement.

Examples:

• If user is active → shorter delays
• If user is cold → longer delays
• If user is highly engaged → send follow-up sooner

How Frequency Logic Works Inside Brevo

Frequency logic controls how often subscribers receive emails from your automation system. It protects your list from email fatigue and reduces spam complaints.

1. Frequency Caps

You can set a limit such as:

• Max 1 email per day
• Max 3 emails per week
• Max 10 emails per month

Frequency caps prevent oversending while maintaining workflow timing.

2. Workflow-Level Frequency Control

Each workflow can have its own frequency rules. For example:

• Welcome journey: 1 email daily
• Re-engagement journey: 2–3 emails weekly
• Sales journey: 1 email every 48 hours

3. Global Sending Limits

Brevo allows you to apply global rules for all automations:

• No more than X emails in 48 hours
• No sending to inactive users
• No sending to cold segments

4. Frequency by Engagement Level

High-engagement leads can receive more frequent emails. Cold leads should receive fewer.

Example rules:

• Active 7-day users → send daily
• Active 30-day users → send every 3 days
• Inactive users → send once weekly

How to Structure Multi-Step Timing in Brevo

1. Welcome Flow Timing

• Day 0 → Instant delivery
• Day 1 → Value email
• Day 3 → Story email
• Day 5 → Soft offer
• Day 7 → Call-to-action

This pacing builds trust without overwhelming the user.

2. Lead Nurture Timing

A good nurture flow sends emails every 2–4 days.

3. High-Intent Sales Timing

For pricing visits or product views:

• Email 1 → Instant
• Email 2 → 12–24 hours
• Email 3 → 48 hours

4. Re-Engagement Timing

Inactive users require slower pacing:

• Email 1 → After 30 days inactivity
• Email 2 → After 3 days
• Email 3 → After 7 days

Advanced Timing Techniques

1. Time-of-Day Optimization

Send emails during your audience's most active hours. Use Brevo analytics to identify peak engagement times.

2. Send-Time Optimization

For higher plans, Brevo optimizes delivery based on each user’s open history.

3. Behavior-Based Pacing

If a user opens faster, reduce delay. If user is slow, increase delay.
