GridInbox vs MailMask

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.

MailMask creates unique email aliases that forward incoming messages to an existing mailbox. Aliases can be created, disabled, or removed; disabling one immediately stops new mail from being accepted. MailMask is not a mailbox or email-provider replacement, and it cannot send messages from alias addresses. The service says it processes email only for forwarding and does not retain message content longer than technically necessary for delivery. Its infrastructure and data handling remain within Europe, under European law including the GDPR. MailMask says it uses no advertising, analytics, or third-party tracking, and does not sell or share user data. The Free plan costs nothing for aliases and forwarding, with no price or usage limits stated. The operator describes it as a personal risk-reduction layer, not for critical, account-recovery, or mission-critical communication. Availability is best-effort, and uninterrupted service is not guaranteed.
