GridInbox

What GridInbox is

GridInbox is a shared email workspace for teams handling customer conversations sent to business addresses such as support@, sales@ and billing@. Team members can assign conversations, see who is handling them and reply from the appropriate business address. Its two-way aliases let users receive mail at an alias and send or reply from that same address.

GridInbox also provides a REST API for creating and deleting aliases, reading messages and sending email programmatically. It extracts one-time passwords and verification codes from incoming email for access through the dashboard or API. The Free plan includes REST API access, five aliases, 10 outbound emails per month, 50 inbound emails per month, 512MB of storage and a 5 MiB attachment limit. Pro costs $19 a month and adds OTP auto-extraction, unlimited aliases, 5GB storage and up to three custom domains. Team costs $99 a month and includes five seats with role-based access control, per-inbox permissions and up to 10 custom domains.

The maker describes use cases including e-commerce operations, QA automation, agencies and solopreneurs. GridInbox is intended for transactional and operational email; bulk marketing emails are prohibited. It runs on the web and provides API access. The maker is Quanta Flow Inc., based in Sheridan, Wyoming.

Who it suits

GridInbox suits teams and individuals managing operational conversations across business email addresses, including e-commerce operators, QA automation users, agencies and solopreneurs. Its API and OTP extraction can also suit workflows that need programmatic email access or verification codes.

Limits

The Free plan is limited to 10 outbound and 50 inbound emails per month, five aliases, 512MB storage and 5 MiB attachments. It uses GridInbox system domains. Pro is listed at $19 a month with a 7-day free trial.

Getting started

1. Visit the GridInbox website.
2. Start with the Free plan or choose a paid plan.
3. Use the web workspace to manage conversations and aliases.

Verdict

GridInbox is a fit for teams that need shared handling of operational email, alias replies and API access. The free plan provides a way to start, while Pro adds OTP extraction and custom domains. Teams needing multiple users with role controls should consider Team; bulk marketing email is outside its permitted use.
