Usually, no — you do not need dedicated IPs for transactional email.
When shared IPs are fine
For most senders, a shared IP is the better choice because:
- Transactional volume is often too low to justify a dedicated IP
- Reputable email service providers manage shared IP reputation well
- You benefit from the provider’s existing sender reputation and infrastructure
- It’s simpler and cheaper to maintain
When a dedicated IP makes sense
A dedicated IP can be worth it if you:
- Send very high volume consistently
- Need full control over your sending reputation
- Want to separate your traffic from other senders entirely
- Have strict compliance or deliverability requirements
- Send enough volume to keep the IP “warmed up” and active
Important note
For transactional email, reputation is more important than IP ownership. Inbox placement depends heavily on:
- Authentication: SPF, DKIM, DMARC
- Low complaint and bounce rates
- Consistent sending patterns
- Good list hygiene
- Engagement and content quality
If you send only password resets, receipts, alerts, and similar messages, a shared IP is usually best unless your volume is large enough to support a dedicated IP.
If you want, I can also tell you roughly what sending volume justifies a dedicated IP.
