Mailroomly or a sending service plus a shared inbox
Many teams pair a sending service, such as SendGrid, Mailgun, Postmark or Resend, with a shared inbox such as Missive or Front, plus a newsletter tool. Mailroomly does all three on one plan, with every reply next to what was sent. The separate stack costs more per user and needs glue code between tools.

Mailroomly and a separate stack, side by side
| What you need | Mailroomly | Sending service + shared inbox |
|---|---|---|
| Bills | One plan | Two or three, and the inbox per user |
| Users who answer | 1 to 10 users included, then €6 a month each | Missive from $14 per user, Front from $25 per seat, both billed yearly |
| Sending price | From €12 for 10,000 emails | Resend from $20 for 50,000; Mailgun from $15 and Postmark from $15 for 10,000 |
| A reply to your app’s email | In the thread with the email it answers | In the inbox, apart from the email it answers |
| What you build between them | Nothing | Webhooks and scripts between the tools |
| AI agents with approval | Over MCP or the API, in the same threads | Depends on each tool |

When a separate stack fits better
- Your team needs inbox features Mailroomly doesn’t have, such as shared calendars, chat or CRM rules.
- You need personal mailboxes too: Mailroomly is for shared addresses, not personal email.
- You send at a volume where a sending service’s bulk prices matter more than the inbox.
Questions about one plan instead of three tools
Can I keep my shared inbox for now?
Yes. Start with your apps’ email, then move an address when your team is ready.
How are users counted?
Each plan includes users (1 on Solo, 3 on Team, 10 on Business), and each extra user costs €6 a month.
