Email platform where several team members can send from their own addresses to one shared list

Mailchimp is a good fit if you mean a shared mailing list for newsletters or other bulk emails: invite each teammate with their own login, share one audience, and set the sender name and address for each campaign. The sender address may need verification. (mailchimp.com)

If you mean several people sending individual emails to contacts from their own mailboxes while keeping a shared contact list, Brevo may fit better; it supports one-to-one emails from connected individual mailboxes as well as campaigns to lists. (help.brevo.com)

Are you sending newsletters to the list, or personal one-to-one emails?

The best fit is a Google Group (or another mailing-list service). It gives you one shared address that delivers to every member, and members can post from their own addresses.

• Google Groups (free with Google Workspace or a personal Google account): A Google Group is comprised of the email addresses of its members but it also has its own email address. By default, the sender shows as the author, and the group's settings decide who can post. The author's address is the default sender setting, which suits discussion groups. Messages sent to the group address are forwarded to all members of the group. Group managers can also set up monitoring so an administrator reviews emails before they go out to the entire group. Keep in mind that Gmail caps daily recipients, but a message to a Google Group address generally counts as one recipient from the sender's side, since the group handles distribution.

• Dedicated group-email or mailing-list services: If you need more control, such as archives, digests, or a branded footer, look at hosted list tools. One comparison lists Simplelists at $13/mo, along with free self-hosted Mailman, which is open-source software you run on your own server.

• Not a good fit: shared inbox tools. Tools like Front, Help Scout, or Missive are built for incoming mail, where one person owns each reply. Shared inbox software is a tool that lets several people manage, assign and reply to one team address. That is a different job from broadcasting from many senders to one list.

For most teams, I'd start with a Google Group. If you're on Microsoft 365, a Microsoft 365 Group or distribution list does the same job, though I didn't verify its current features in this search. If you tell me your email provider and roughly how many members there are, I can narrow this down.

To manage a shared email list where multiple team members can send messages from their own (or a shared) address without the "reply-all" chaos or missed communications, you need Shared Inbox software.

These platforms are specifically designed to allow your team to collaborate on emails behind the scenes—assigning tasks, leaving internal notes, and drafting responses together—without the recipients ever knowing.

Top Recommendations for 2026

1. Best for Collaboration & Workflow: Front

Front is widely considered the leader for teams that want a "shared inbox" that still feels like email.

• Why it works: It allows you to manage multiple channels (email, SMS, WhatsApp) in one place. You can assign emails to specific team members, discuss them internally with comments, and draft replies together.
• Best for: Professional services, sales, and operations teams that need high-level collaboration and automation.

2. Best for Simplicity & Support: Help Scout

Help Scout is designed to make customer support feel personal, like a standard email conversation, while providing the power of a ticketing system.

• Why it works: It is very intuitive and removes the "clunky" feel of traditional help desks. It includes collision detection (to prevent two people from replying to the same email), saved replies (macros), and a built-in knowledge base.
• Best for: Small-to-medium teams that want a clean, email-first interface without overwhelming complexity.

3. Best for Teams Already in Gmail: Hiver

If your team is already deeply integrated into Google Workspace, Hiver is a popular choice because it lives directly inside your existing Gmail interface.

• Why it works: You don’t need to switch to a new tool/tab. It adds shared inbox features like assignments, email status tracking, and notes directly into the Gmail dashboard.
• Best for: Gmail-native teams who want to keep their existing workflow but add team collaboration features.

4. Best for All-in-One Team Communication: Missive

Missive is unique because it integrates chat and email into a single, cohesive experience.

• Why it works: It allows for "live co-drafting," where you and a colleague can type a response together in real-time. It also supports SMS, WhatsApp, and social media channels.
• Best for: Fast-moving teams that want to eliminate forwarding and CC chains entirely by discussing tasks right inside the email thread.

Comparison of Approaches

Important Recommendation

• If you are just getting started: Try the native Microsoft 365 Shared Mailbox or Google Workspace Shared Inbox first. They are free, built into the platforms you already use, and satisfy the needs of many smaller teams.
• If you are struggling with "who is doing what": If you frequently experience duplicate replies, lost messages, or messy internal "forwarding chains," it is time to upgrade to a dedicated tool like Front, Help Scout, or Missive.

Avoid using standard email groups or distribution lists if you have more than 2-3 people. They are not designed for collaboration and will almost certainly lead to confusion, missed emails, or duplicate work as your team grows.

Mailjet looks like a good fit: it offers shared workspaces and team roles, and lets you manage sender addresses alongside shared contact lists. Team members can collaborate on campaigns sent to the same list. ¹²

If you mean each person sends individual, one-to-one emails (rather than newsletter campaigns), lemlist may fit better: users can send from their own addresses while sharing lead data within one team. ⁶
