Anypost

Anypost is a transactional and broadcast email API and SMTP service built for developers and teams who need reliable email delivery without legacy pricing. Anypost gives you a modern email infrastructure platform for sending everything from password resets and receipts to newsletters and marketing campaigns, backed by the same delivery pipeline and event reporting regardless of which transport you use. Two ways to send: a fast, JSON-based HTTP API (POST to api.anypost.com/v1/email) for teams building custom integrations, or standard SMTP for plugging into existing apps and off-the-shelf software with zero code changes. One API key authenticates both, and official SDKs are available for TypeScript, Python, PHP, Ruby, Go, Rust, Java, and C#, alongside full support for plain HTTP requests. Anypost's core object model, Team, Domain, API Key, Message, Event, and Webhook, gives you strict data isolation and real-time delivery visibility. Every send generates trackable events (sent, delivered, bounced, complained, opened, clicked) pushed to your webhook endpoint the moment they happen, so you always know what's landing and what isn't. Built-in suppression management automatically protects your sending reputation by blocking mail to addresses that hard-bounce or complain. Deliverability is handled for you: automatic DKIM/SPF signing and managed sending-reputation warmup come standard, so new senders don't have to manually configure authentication or slowly build trust with mailbox providers. Templates let you store reusable subject lines, HTML, and text with variable placeholders, and Anypost's open-source emailmd renderer lets you write plain Markdown and get back HTML tested across Gmail, Outlook, Apple Mail, Yahoo, Thunderbird, and mobile clients, plus an AI template generator that turns a plain-language description into a full email template. What makes Anypost different from legacy email APIs is infrastructure: it runs on bare metal rather than marked-up cloud infrastructure, which is how it keeps pricing a fraction of what established providers charge. Every account starts free for up to 3,000 messages a month, with adaptive daily sending limits and flexible prepaid overage credits for teams that scale beyond it. Anypost is an over-deliver, under-budget alternative to legacy transactional and broadcast email providers, combining API and SMTP flexibility, built-in deliverability tooling, real-time event tracking, and developer-friendly pricing in one platform.

Email Deliverability Tool | by SMTPCart

The Email Deliverability Tool by SMTPCart is an instant, web-based diagnostic utility engineered to evaluate email authentication protocols, server infrastructure, sender reputation, and message content health before dispatching live campaigns. Built with a focus on simplicity and friction-free operations, the tool requires no user registration, sign-up, or account creation, allowing email marketers, systems administrators, and software developers to perform on-demand deliverability audits in seconds. To initiate an assessment, the user generates a unique diagnostic mailbox address directly through the platform and dispatches a single test email from their mail client, server, or sending software. Upon receiving the message, the tool executes a comprehensive series of real-time server and content checks, calculating an overall performance score out of 100% alongside a downloadable, audit-ready PDF report detailing technical specifications and actionable recommendations. The utility performs an exhaustive technical evaluation to ensure messages consistently reach recipient inboxes rather than spam folders. It inspects Sender Policy Framework (SPF) records to verify server authorization, checks DomainKeys Identified Mail (DKIM) cryptographic signatures for message integrity, and evaluates Domain-based Message Authentication, Reporting, and Conformance (DMARC) alignment to protect against domain spoofing. Beyond protocol alignment, the tool conducts low-level network checks on the sending infrastructure, validating reverse DNS (PTR) records, checking active Transport Layer Security (TLS) encryption during transit, and confirming compliance with RFC-compliant one-click unsubscribe headers. To ensure complete threat visibility, the platform scans sending IP addresses across 20 active IP blocklists, queries the Spamhaus domain blocklist, and uses an integrated SpamAssassin rule engine to analyze subject lines, body text, and HTML markup for spam triggers, giving senders the clarity required to protect their domain reputation and optimize inbox placement.
