EmailAlias.io vs GridInbox

EmailAlias.io creates private forwarding aliases so services do not receive a user’s real email address. Mail forwards to an existing provider such as Gmail, Outlook, ProtonMail, Yahoo, or another inbox. Sender exposure scoring looks for risky domains, typosquatting, phishing keywords, and other leak signals, while machine-learning spam detection blocks phishing, malware, and unwanted mail before forwarding. The service says it does not read, analyze, or store forwarded message bodies or attachments and keeps delivery metadata; email metadata logs are retained for 90 days. Premium users can add up to five custom domains, send and reply from aliases, and use the REST API and MCP access. The Free plan includes 10 aliases. Premium costs $4 a month. Browser extensions support Chrome, Firefox, and Edge; no mobile apps are listed.

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.
