Frequently asked questions
Why do email reply rates drop in December?
December email reply rates drop due to holiday seasonality, not deliverability issues. People are on vacation, inboxes are flooded with promotional emails (30%+ increase), and attention is focused on family rather than business. Conversion rates typically drop from 6.1% to 2.9% during this period.
Is my email deliverability broken in December?
No, December email performance drops are almost always seasonal, not technical. Global inbox placement rates remain stable at around 84%. The drop in responses is due to recipient behavior (vacations, holiday distractions) rather than emails going to spam.
When do email reply rates return to normal after holidays?
Email reply rates typically begin recovering in the second week of January and return to normal levels by late January or early February. The first week of January often has lower-than-usual engagement as people catch up on holiday backlogs.
Should I pause email campaigns in December?
Not necessarily. While response rates are lower, some industries see success with holiday-themed campaigns. Consider reducing volume, adjusting expectations, and focusing on relationship-building rather than hard sales during the holiday period.
