CloudMailin review
A strong fit for teams turning inbound email into application workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
CloudMailin is an email API for developers building applications that need programmable email receiving, parsing, and transactional sending. Its core capability converts inbound messages into HTTP POST webhooks in JSON, multipart, or raw formats. Teams can also send outbound email through a REST API or SMTP relay, making it suitable for workflows that combine inbound processing with transactional communication.
Pricing starts with a Free plan supporting 10,000 emails per month, 512KB per message, and no credit card required. The seven-day free trial applies to the paid offering. Starter costs $25 per month for 10,000 emails, 2MB messages, and full-text search. Professional costs $45 per month for 20,000 emails and 10MB messages, while Premium costs $85 per month for 40,000 emails and 50MB messages. Corporate supports 100,000 to 7 million emails per month. Dedicated costs $1,499 per month and adds a dedicated cluster, higher throughput, and full control.
CloudMailin’s broader feature set covers delivery, bounce, open, and click webhooks; reusable layouts and templates; custom domains; catch-all receiving; delivery-status history; and full-text search. Attachments can be stored in Amazon S3, Microsoft Azure Blob Storage, or Google Cloud Storage. These capabilities suit teams that need inbound email conversion as a primary workflow and want outbound delivery in the same service. Organizations focused only on basic outbound sending may find the inbound-oriented feature set less relevant, while high-volume applications should assess the higher-tier options and throughput requirements.
