Overview
Deliverability is a global configuration setting in Journeys that controls when and how often your messages are delivered. It ensures that your campaigns respect sending limits, timing restrictions, and time zone alignment, helping you avoid over-sending and improve customer experience.
By using deliverability settings, you can define daily caps, add gaps between messages, and control delivery by time of day and day of week.
How it works
Deliverability applies to the entire journey, not to individual message blocks.
When a user reaches a messaging step (send email, sms, push notification), the system checks the journey-level deliverability rules:
If sending is allowed (within limits, time window, and days), the message is delivered immediately.
If sending is not allowed (e.g., daily limit reached, outside allowed hours, or blocked day), the message is delayed until the next available delivery window.
This ensures consistency across all messages in the journey and prevents users from receiving messages at undesired times.
Getting started
Go to Journeys and open an existing workflow (or create a new one).
In the top bar, select Deliverability.
Configure the sending rules you want to apply to this journey.
Save your settings.
📘 Good to know
Deliverability rules apply globally to all messages (email, sms, push notifications) in the journey.
If no deliverability rules are defined, messages will be sent immediately whenever a user reaches a messaging step.
Configuring deliverability
Deliverability settings apply to the entire journey, not to individual messages. This means all emails, SMS, and push notification actions within the journey will follow the same global sending rules.
To configure deliverability:
Set a daily limit
Define the maximum number of emails a user can receive per day from this journey.
Example: “Limit to 50 emails per day.”
Define a minimum time gap between emails
Prevents multiple emails from being sent too close together.
Example: “Wait at least 2 hours before the next email is sent.”
Send in the recipient’s timezone
Ensures messages are delivered at the correct local time.
If the recipient’s timezone is unknown, you can set a fallback timezone (e.g., GMT+02:00 Europe/Helsinki).
Set sending windows
Choose the hours when emails can be sent (e.g., only between 9:00 AM and 6:00 PM).
Prevents messages from being delivered at night or outside working hours.
Select sending days
Define which days of the week messages may be delivered.
Example: Only Monday to Friday, excluding weekends.
📘 Good to know
Deliverability rules apply to all actions in the journey.
If a message falls outside the allowed sending time or day, it will be held until the next available delivery window.
If the daily limit is reached, additional messages will not be sent until the next day.
Deliverability best practices
Use daily limits to protect your audience from over-communication.
Apply a minimum time gap to avoid clustering multiple emails in short periods.
Always enable recipient timezone delivery for global audiences.
Restrict sending windows to business hours for higher engagement.
Avoid sending on weekends or holidays unless your product or audience specifically benefits from it.
