CloudMailin vs Maileroo

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.

Maileroo provides SMTP relay and Email API services for transactional and marketing email, along with inbound routing and testing tools. Sending features include streams, bounce and complaint handling, suppression handling, and resending messages from logs. Inbound routing can apply custom expression rules, catch-all or wildcard matching, forwarding, parsed JSON webhooks and automatic retries, with SPF and DKIM enforcement and spam checking.

Testing tools include SMTP and MX sinks, light and dark client previews, spam scoring, authentication and alignment checks, link and RBL checks, and API and CI/CD access. Maileroo also provides click and open tracking, delivery event reporting, searchable activity, data exports and real-time analytics. Listed integrations include SDKs for several programming languages and connections to WordPress, WooCommerce, Zapier, Make and Pabbly. Security options include encrypted storage, two-factor authentication, passkeys, SAML SSO, scoped API keys, role-based permissions and IP restrictions. The free plan includes monthly quotas; paid plans start at $10 a month. Monthly and hourly sending limits apply, and mail over the monthly quota is not sent until reset or plan upgrade.
