Learn how to request, warm up, and monitor a Dedicated IP for emails sent from Crisp.

A Dedicated IP lets Crisp send your outbound emails from an IP address assigned to your workspace instead of a shared pool. This gives you more control over sender reputation, but it also means your sending behavior directly shapes the IP's deliverability.

In this guide:

• Understand why Dedicated IPs matter → reputation, limits, and deliverability control
• Request a Dedicated IP → install the plugin and request assignment
• Warm up your Dedicated IP → build reputation progressively
• Monitor your Dedicated IP reputation → check reputation and delivery logs
• Understand Dedicated IP limits → default Campaign recipient limits and upgrades

Understand why Dedicated IPs matter

By default, Crisp sends emails through shared IP pools. This is simple and cost-effective, but the IP used to send your emails may also be used by other Crisp users. Crisp separates senders into reputation pools to reduce risk, but some teams prefer to fully control their own sending reputation.

A Dedicated IP starts with no reputation history. It is neither good nor bad at first. Mailbox providers use the IP address, domain authentication, list quality, engagement, bounces, and complaints to evaluate whether future emails should reach the inbox or spam folder.

A Dedicated IP can help you:

• Control sender reputation → your delivery reputation is tied to your own sending behavior
• Increase recipient limits → one-shot Campaigns can be sent to higher recipient counts
• Reduce shared-pool exposure → other Crisp users do not affect your assigned IP reputation

Request a Dedicated IP

You can request the Dedicated IP from your Crisp dashboard.

1. Open app.crisp.chat.
2. Go to Plugins.
3. Search for the Dedicated Email IP plugin.
4. Install the plugin.
5. Go to Settings → Email Settings → Email Delivery.
6. Click Request a dedicated IP assignment.
7. Wait for Crisp to assign and configure the IP.

Once the assignment is complete, Crisp displays the Dedicated IP status in the same email delivery settings.

Warm up your Dedicated IP

A new Dedicated IP needs to build reputation gradually. Sending a large Campaign immediately after assignment can trigger spam filters because mailbox providers have not seen enough healthy traffic from that IP yet.

When it comes to IP warm-up, slower is safer.

If you mainly use Crisp for one-to-one conversations, you can start using the Dedicated IP right away. Regular Inbox replies and transcript emails are useful low-volume traffic that helps the IP build reputation naturally.

If you plan to send Campaigns, start with a smaller, highly engaged audience before increasing volume. You can also send a few test messages to personal email addresses first. Some early messages may land in spam while the IP is still unknown; if that happens during internal tests, move them back to the inbox.

Good warm-up practices:

• Start with engaged recipients → send first to contacts who usually open, click, or reply
• Keep volume low at the beginning → avoid sending your maximum Campaign volume from day one
• Increase gradually → double volume every three to four days only if delivery looks healthy
• Do not force volume → natural daily fluctuations are better than padding a send with low-quality recipients
• Monitor bounces and complaints → pause or reduce sending if policy blocks, bounces, or complaints increase

If deliverability issues appear, reduce volume and troubleshoot the affected mailbox providers before resuming. Resume sending only after the cause is fixed.

Monitor your Dedicated IP reputation

You can monitor your Dedicated IP reputation and recent delivery errors from Crisp.

1. Open app.crisp.chat.
2. Go to Settings → Email Settings → Email Deliverability.
3. Review the reputation status and any recent delivery logs.

Understand Dedicated IP limits

By default, a Dedicated IP can be used to send one-shot Campaigns to up to 100,000 recipients per Campaign, depending on your plan and account status.

You can review or increase eligible limits from app.crisp.chat under Settings → Workspace Settings → Data, Limits & Legal.
