Team Email Testing
Made Simple
Shared mailboxes, role-based access, and per-member permissions. Your entire team can inspect, debug, and collaborate on email testing without stepping on each other's toes.
Start Free — Invite Your TeamCollaboration built into every layer
SendPit is designed from the ground up for teams. Organizations, roles, and mailbox-level permissions give you fine-grained control over who sees what.
Organization-Level Multi-Tenancy
Every team gets its own organization. Your mailboxes, members, and billing are completely isolated from other organizations. When you register, SendPit automatically creates your organization and assigns you as the owner. From there, you build your team by inviting colleagues, each of whom joins your organization and gets access only to the mailboxes you choose. No cross-contamination, no accidental exposure of another team's test data.
Role-Based Access Control
Three distinct roles keep responsibilities clear. The org-owner has full control: create and delete mailboxes, manage billing, and add or remove team members. The org-billing role is purpose-built for finance teams who need to manage subscriptions and invoices without touching technical settings. The org-member role is for developers and testers who need mailbox access but should not modify organization-level settings. Each role carries exactly the permissions it needs and nothing more.
Mailbox-Level Permissions
Organization membership does not mean access to every mailbox. SendPit uses a mailbox-user pivot that lets you invite specific people to specific mailboxes. A frontend developer working on the password reset flow only needs access to the staging mailbox, not the QA regression mailbox. Owners and members with the right permissions can view mailbox contents, see SMTP credentials, and regenerate those credentials independently per mailbox.
Invitation-Only Access
There is no open registration to an existing organization. Team members join only when explicitly invited by someone with the appropriate permissions. Invitations are sent by email, and the recipient can accept or decline. This keeps your test environment locked down to the people who actually need it. No one stumbles into your organization by accident, and you always know exactly who has access.
How teams use SendPit
Different roles, different workflows, one shared platform. Here is how each part of your team benefits from collaborative email testing.
Developers
Each developer on your team points their feature branch at a shared mailbox. No more "which email was mine?" confusion. When you trigger a password reset or a welcome email from your local environment, it lands in the same mailbox your teammates can see. You can inspect HTML rendering, verify dynamic content like tokens and URLs, and check headers for correct sender addresses. If a colleague needs to reproduce your bug, they can see the exact email you sent without asking you to forward it.
QA Engineers
During testing sprints, QA engineers need to verify that emails contain the right content, the right links, and the right formatting. With SendPit, they open the mailbox, find the email triggered by their test case, and inspect it directly in the browser. No need for backend access. No need to ask a developer to check server logs. If something looks wrong, they flag it immediately with a link to the specific email. The feedback loop between QA and development shrinks from hours to minutes.
DevOps
Staging environments often use real SMTP providers or disabled email entirely. Both approaches have problems: one risks sending test emails to real users, the other means you cannot verify email flows at all. SendPit gives DevOps teams a dedicated SMTP endpoint for each environment. Point your staging config at SendPit, and every email gets captured safely. Monitor email volume, verify that deployment changes did not break transactional flows, and rotate credentials without disrupting the rest of the team.
Managers
Product managers and team leads often need to review email templates and transactional copy before launch. With SendPit, they do not need to set up a local development environment or ask a developer to send them a screenshot. They log in, open the mailbox, and see the rendered email exactly as a user would. Review the subject line, check the call-to-action, verify that the branding is correct. All without any technical setup whatsoever.
Shared mailbox features
Mailboxes are the core unit in SendPit. Each one is a self-contained SMTP endpoint with its own credentials, its own member list, and its own captured emails.
Multiple Mailboxes Per Organization
Create separate mailboxes for different environments, projects, or teams. A staging mailbox, a QA mailbox, a feature-branch mailbox. Each one operates independently with its own SMTP credentials and captured email stream. Organize your email testing the same way you organize your code.
Per-Mailbox Member Management
Control exactly who has access to each mailbox. Invite team members to specific mailboxes, remove them when projects wrap up, and keep your test data scoped to the people who actually need it. The mailbox-user relationship is independent of organization roles, giving you fine-grained control.
Shareable Email Links
Found a rendering bug in a test email? Share a direct link with your teammate. No need to describe the issue in a Slack message or take a screenshot. They click the link, see the exact same email you see, and the conversation happens around the actual artifact. Fast, precise, and context-rich debugging.
Credential Rotation Without Disruption
When a team member leaves or credentials need to be rotated for security reasons, regenerate SMTP credentials for any mailbox instantly. The new credentials are available immediately, and previously captured emails remain intact. Update your environment configuration and you are back in business. No downtime, no data loss.
Security you can trust
Collaboration does not mean compromising on security. SendPit enforces strict access controls at every level.
Encrypted SMTP Credentials
All SMTP credentials are encrypted at rest using AES-256 encryption. Passwords are never stored in plain text. When you view credentials in the dashboard, they are decrypted on the fly and displayed only to users with the appropriate mailbox permissions. Even database access does not expose raw credentials.
Role-Based Authorization Policies
Every action in SendPit is checked against authorization policies. Creating a mailbox requires the org-create-mailbox permission. Viewing credentials requires membership in the mailbox-user pivot. Deleting a mailbox requires elevated permissions. These policies are enforced server-side, so no client-side workaround can bypass them.
Invitation-Only Organization Access
Organizations are closed by default. New users cannot join an organization without an explicit invitation from an authorized member. This prevents unauthorized access to your test email data. Every person in your organization was deliberately added by someone with permission to do so.
Instant Credential Regeneration
If credentials are compromised or a team member departs, regenerate the SMTP username and password for any mailbox with a single click. The old credentials are immediately invalidated. Auto-generated credentials use cryptographically secure random strings: a 16-character username prefixed with mb_ and a 32-character password.
Plans for teams of every size
The free plan includes one user, perfect for solo developers and personal projects. Paid plans unlock additional team members, more mailboxes, and higher email retention limits. Whether you are a two-person startup or a growing engineering team, there is a plan that fits your workflow.
