GridInbox vs TMailr

GridInbox is a shared email workspace for handling customer conversations sent to business addresses such as support@, sales@, and billing@. Team members can assign conversations, see who is handling them, and send or reply from the address where a message arrived. Its REST API can create and delete aliases, read messages, and send email programmatically. GridInbox also extracts one-time passwords and verification codes from incoming email for access through its dashboard or API. The Free plan costs nothing and includes five aliases, 10 outbound and 50 inbound messages per month, 512MB of storage, a 5 MiB attachment limit, and REST API access. Pro costs $19 a month and includes unlimited aliases, OTP extraction, 5GB storage, and up to three custom domains. Team costs $99 a month and includes five seats with role-based access control and up to 10 custom domains. GridInbox is designed for transactional and operational email; bulk marketing email is prohibited. It runs on the web and offers API access.

TMailr combines receive-only temporary inboxes, masked forwarding aliases, email deliverability checks, and a developer sandbox on the web and through an API. Temporary inboxes use private links, receive mail only, and disappear when they expire. Free inboxes last 60 minutes by default, can be extended to 24 hours, and hold up to 50 messages; Pro inboxes are described as effectively unlimited and remain active while subscribed. Masked aliases forward messages to a real mailbox, can be paused or blocked separately, and keep the forwarding address out of TMailr pages and API responses. Deliverability tools include Gmail inbox tests, domain checks for MX, SPF, DMARC, MTA-STS, and TLS, plus header, address, and DMARC tools. Developers get test and live keys, JavaScript examples, polling, and signed webhooks. Incoming HTML is sanitized, remote images are blocked until requested, links show destinations, and attachments are virus-scanned; executable files are refused.
