Shared vs Dedicated IP for Business Email

When you send email, it goes out from a sending IP address - and whether that IP is shared or dedicated affects how mailbox providers treat your mail. Here's the difference and how to choose.

What the two options mean

• Shared IP - your mail goes out from an IP used by many senders. The reputation is pooled across everyone on it.
• Dedicated IP - an IP used only by you. Its reputation reflects only your sending.

When a shared IP is the right choice

For most businesses - especially those sending normal volumes of everyday mail - a well-managed shared IP is ideal:

• The provider maintains the IP's reputation across a large, vetted pool
• You benefit from established, warm reputation immediately
• There's nothing to warm up or maintain yourself

The key phrase is well-managed. A reputable host keeps bad senders off its shared pools, so you're in good company. See how to improve email deliverability.

When a dedicated IP makes sense

A dedicated IP is worth it mainly when you send high, consistent volume and want full control of your reputation - for example, large marketing or transactional programmes. The trade-offs:

• You must warm it up gradually to build reputation - see how to warm up a new email domain
• You need steady volume to keep the reputation healthy
• Any sending mistakes land squarely on you

The reputation that really matters: your domain

Whichever IP you use, your domain reputation - built on authentication and good sending habits - carries the most weight today. Get the fundamentals right first: see SPF, DKIM and DMARC explained and transactional vs marketing email.
