Smart domain warmup

Warm Up Your Domain — Scale Sending with Inbox Confidence

In Arsel, domain warmup starts automatically after DNS verification — gradually raising your daily send cap while monitoring delivery and bounces, so inbox providers trust your domain before big campaigns.

The new domain problem

High-volume sending from a new domain can land you in spam

If you're launching email campaigns or sending from a fresh domain, these challenges won't go away by blasting volume all at once

The problem in one line
The more you send without protection, the higher the risk of missing the inbox and losing customers.

Protection isn't a luxury — it's the foundation for reaching inboxes and scaling sustainably.

A new domain with no sending history

Inbox providers don't know you yet — sudden high volume reads as a risk signal.

Good emails still hit spam

Even with great content, sending too much too soon hurts inbox placement.

No clear safe daily send limit

You guess the right cap or copy generic warmup schedules that don't fit your lists or audience.

Manual warmup eats your time

Spreadsheets, manual staggered sends, and daily check-ins — repetitive work far from growing your business.

Bounces or complaints stop your ramp

A spike in bounces or complaints can pause sending and damage domain reputation.

No visibility into send health

You can't tell if delivery is healthy today, or when it's safe to increase volume.

The solution

Smart warmup — from first send to full campaign volume

Arsel manages your domain warmup journey — gradual volume increases, daily monitoring, and clear stats for every domain.

Smart daily send limit increases

Your daily cap rises automatically day by day — only when delivery stays healthy — until you reach full volume with confidence.
