Time Zone Segmentation

Send Messages When Customers Are Most Likely To Engage

Sending messages at the right time matters. A campaign sent at 9 a.m. ET works great for your customers in New York, but is likely too early for customers in Los Angeles. The time zone segmentation use case automatically groups your customers by their local time zones based on geographic location data, allowing you to send messages at appropriate times for each customer’s location across email, SMS, and weblayers when engagement peaks.

Why Marketers Turn to Bloomreach for Location-Based Send Time Optimization

Global brands struggle with message timing — sending campaigns might work for one time zone but not another, leading to opt-outs and frustration. Manual time zone segmentation requires constant maintenance as customers move or travel.

Bloomreach’s marketing automation solution allows you to group customers by local time zones using location data from customer attributes and behavioral events. You schedule one campaign that delivers at the optimal hour for each recipient. Prebuilt US, EU, and combined segmentations work immediately, with customizable options for global expansion.

Prebuilt Use Case

Automatically group customers by local time zones using intelligent cascading logic that checks multiple data sources. Bloomreach’s marketing automation solution first examines customer attributes (country for EU, state for US), then falls back to behavioral data from session_start events to determine the most common location. Three prebuilt segmentations are ready to use immediately:

US time zones (EST, CST, MST, PST)
EU time zones (covering major European regions)
A combined US + EU segmentation for global campaigns

For example, schedule a product launch email for 10 a.m. and each customer receives it at 10 a.m. in their local time (e.g., New York customers at 10 a.m. EST, London customers at 10 a.m. GMT). Customize by adding new time zones like JST or AEST, or extend the cascading logic with additional data sources for more precise targeting.

How It Works

Automatic detection – Bloomreach automatically detects customer time zones from location data, IP addresses, and profile information, creating accurate geographic segments without manual setup.

Silent hours configuration – Configure silent hours to prevent messages during inappropriate local times, ensuring respectful communication that builds customer trust.

Segment creation – Create time zone-based customer segments using prebuilt templates for major geographic regions (US, EU, US + EU time zones) or custom configurations for specific markets.
