If your emails go out later than scheduled or sit in a queue for a while, this is usually a temporary spike in sending traffic on our side.
Your deliverability is not affected — we log every email and ensure it is delivered, even with a slight delay.
Tip: schedule your campaigns 1–2 hours before your target send time to absorb any delay. If your emails are not sending at all (not just delayed), contact support and we'll check your account.
