CloudMailin vs MailParse

CloudMailin receives email and delivers it to web applications through HTTP POST webhooks. Inbound messages can arrive as JSON, multipart form data, or raw text; attachments can be forwarded to a webhook or stored in Amazon S3, Azure Storage, or Google Cloud Storage. It also sends transactional email through an API or SMTP relay. Outbound tools include spam checks, link and open tracking, bounce handling, reporting, tagging, and priority queues. Inbound delivery history includes 30 days of searchable records with error and retry details, while metadata retention is listed as 60 days. CloudMailin says its inbound service works with any language or framework, naming examples from Node.js and Python to Java and C#. The service was founded in 2010 and is available through an API and the web. A free plan allows 10,000 emails per month and 512KB per message. Paid plans start at $25 a month; the listed options include different email and message-size limits. A seven-day trial is also listed.

MailParse receives inbound email and converts MIME messages into structured JSON. It extracts text and HTML bodies, inline images, attachments, headers, and routing details, including nested and multipart messages. Parsed results can be sent by POST to a configured webhook, with exponential-backoff retries and HMAC signature verification, or retrieved through a REST polling API. Polling supports filters for sender, date range, subject, and attachment type, with cursor-based pagination. SPF, DKIM, and DMARC validation, spam scoring, and per-address rules support message handling. Attachments use signed download URLs and are retained for 72 hours by default, with plan-based retention settings. Custom domains require an MX record and ownership verification. If a webhook is unavailable, retries continue for up to 24 hours, with replay and polling recovery. MailParse offers API and web access. Free includes 100 emails monthly; Pro costs $29 per month and Scale $99 per month.
