Mailcast
Randburg, South Africa
What it is
Mailcast is an email routing service available through the web and an API. It can receive messages, forward them, pass them to an existing email service, or deliver them to a website or app through webhooks. Catch-all addresses, regular-expression alias matching, plus addressing, and forwarding to multiple recipients support varied routing setups. Rules can trigger conditional actions and change subjects before forwarding. Webhooks accept parsed email as JSON, form data, or multipart data with attachments, and SMTP sending from alias addresses is supported. Mailcast says TLS protects email during receipt and forwarding, while queued email is encrypted in storage. Successfully processed messages are deleted by default; failed messages and their logs are deleted, and logs are removed after seven days. SPF, DKIM, and DMARC are included on every plan. The Free plan costs nothing, while paid options include Starter at $5 a month, Essential at $9 a month, Premium at $19 a month, and Personal at $24 a year.
