Frequently asked questions

Everything you need to know about SendX and email marketing

How do I enable Spread Sending?

Toggle it on under Campaign Settings, then set your preferred send window and rate.

What’s the ideal spread window length?

It depends on list size and ISP mix. Start with 1‑2 hours for 100k+ contacts and adjust from there.

Will spreading sends delay delivery too much?

Most recipients still get emails within the first hour; the benefit to deliverability outweighs slight delays.

Does Spread Sending help with spam complaints?

Yes. Lower per‑minute volume reduces ISP suspicion and gives you room to react to early complaint signals.

Can I edit the window after the campaign starts?

You can shorten or extend live windows; SendX recalculates pacing instantly.
