The concept of a single best day and time to send an email is misleading. Instead, marketers should vary send times throughout the week to reach different segments of their audience. The key metric is the aggregate number of unique individuals engaged weekly, not the performance of a single blast.

Email providers prioritize senders with high engagement. Sending at least five emails per month generates more opens and clicks, signaling credibility. This counterintuitively leads to higher average open rates and better inbox placement, contrary to the common fear of over-sending.

Focusing on email open rates can lead to clickbait subject lines and weak copy. Instead, orient your entire outreach strategy around getting a reply. This forces you to write more personalized, engaging content that addresses the recipient's specific pain points, leading to actual conversations, not just vanity metrics.

Contrary to the fear of over-sending, emailing at least five times per month improves deliverability. Email providers view consistent recipient engagement (opens, clicks) as a sign of a credible sender, leading to better inbox placement and significantly higher open rates.

Instead of optimizing for a single "best" send time, marketers should vary sending days and times (e.g., evenings, weekends). This strategy acknowledges that different people within your database interact with email at different times, maximizing overall reach and engagement across your entire list.

The common practice of having a fixed daily 'call block' (e.g., 9-10 AM) is fundamentally flawed. If your target prospect has a recurring meeting at that same time, you will never reach them. Effective prospecting requires dynamism; you must vary your outreach times throughout the week to maximize your chances of connecting.

Shift your primary success metric from passive opens to active replies. A reply signifies a genuine two-way conversation and a much deeper level of engagement. Actively inviting responses in your emails transforms a broadcast into a powerful relationship-building tool and provides invaluable audience feedback.

The idea of a single best time to send an email is outdated. Instead, measure success by the weekly aggregate of unique individuals opening your emails. Sending at various days and times hits different audience segments, maximizing your total reach over time.

During BFCM, consumer inboxes are flooded. To break through, brands should send multiple emails per day, including resends (e.g., 3 scheduled emails plus a resend for each). The incremental revenue gained from this high frequency justifies the potential increase in spam complaints.
