Timezone Optimization for Global Outreach

When you send matters as much as what you send. Here's how to time global campaigns.

Best Send Times by Region

US East Coast: 10am-11am EST Tuesday-Thursday. US West Coast: 10am-11am PST. UK/Ireland: 10am-11am GMT. Central Europe: 10am-11am CET. APAC: 10am-11am local time.

The Tuesday-Thursday Effect

Monday inboxes are full from weekend backlog. Friday attention is waning. Tuesday-Thursday consistently outperforms. This holds globally.

Practical Implementation

Segment lists by timezone. Schedule sends in sequences. Or use tools that auto-detect recipient timezone. Don't send at 3am local time—it signals automation and gets ignored.

Follow-Up Timing

First follow-up: 3-4 days after initial send. Second: 1 week after first follow-up. Third: 2 weeks after second. Respect local holidays—no outreach during August in France or Germany.
