Sendfeather

Sendfeather is a transactional email service for product teams. Send receipts, one-time codes, and notifications over SMTP or a single HTTP API call — every message gets a delivery timeline from accepted to delivered, with bounces and complaints handled automatically. Every paid plan includes hosted mailboxes for your domain, so sending and receiving live in one place. Pricing is flat and published: $7 per month for 10,000 emails, $15 for 50,000, and $29 for 100,000.

SendFleet

Amazon SES gives you control over email delivery, but getting everything configured and keeping it running smoothly takes work. SendFleet handles much of that work for you. Connect your AWS account through a CloudFormation stack, and SendFleet helps configure SES, finds a region where you can send, enables suppression and delivery tracking, and submits production access requests when needed. It also monitors bounce and complaint rates and can pause sending before your account reaches AWS review thresholds. From one dashboard, you can manage sending domains, API keys, delivery events and email activity without building and maintaining the infrastructure yourself.

Sendmux

Sendmux gives AI agents their own email inbox and a controlled way to send mail. Each agent can have a dedicated mailbox, read threads, handle attachments, send replies, and react to new messages through webhooks or Server-Sent Events. For teams building agents that need real email in production, that means fewer custom glue scripts and fewer fragile Gmail-style workarounds. Outbound email can run through Gmail OAuth, Outlook OAuth, SMTP providers, or managed Amazon SES. Teams can spread sending across providers with weighted routing, sender-domain routing, health checks, failover, and quotas by second, minute, hour, or day. That matters when one provider is not enough, or when customers already have approved sending infrastructure they want to keep using. Sendmux also gives developers the practical pieces around the inbox: Mailbox, Sending, and Management APIs, OpenAPI docs, SDKs for TypeScript, Python, Go, PHP, and Ruby, the sendmux CLI, MCP tools, and official Sendmux Skills for agent workflows. It is built for AI agent products, automation agencies, platform builders, support agents, scheduling agents, ops workflows, and controlled BYO-provider outbound email setups. Pricing is usage-based, with no per-seat or per-mailbox fees.

sendzovo

Sendzovo is a transactional email platform for developers that combines email sending and email verification in one service. Send password resets, sign-in codes, receipts and account notifications through a REST API or standard SMTP, with code examples for cURL, PHP, Node.js, Python and C# and an official PHP SDK. Recipient verification is built in: Sendzovo can verify each address before a message is sent, checking syntax, domain and MX records, the mailbox on the receiving server, and risk signals such as catch-all domains, disposable inboxes and role-based addresses. Known-bad recipients are skipped instead of bouncing, and hard bounces and spam complaints are suppressed automatically to protect your sender reputation. Sendzovo also includes Message Streams to separate transactional and broadcast email, reusable templates and layouts, delivery tracking for bounces and complaints, webhooks, domain-scoped API keys and DKIM, SPF and DMARC setup guidance. A free plan is available.

Sidemail.io

smtply

SMTPly is email relay software enabling legacy devices to send messages via Microsoft 365 using OAuth2 authentication. Running as a local Windows service, it converts SMTP connections into Microsoft Graph API calls, ensuring data remains local without third-party servers. Its architecture includes an SMTP listener, relay queue with retry logic, and a Graph sender managing OAuth2 tokens for secure delivery. Security features include DPAPI encryption, certificate store integration, and health monitoring for certificate expiration alerts. A live mail tracker provides visibility into relayed messages, while usage reports summarize activity and errors. The software supports STARTTLS, implicit TLS, IP whitelisting, and sender domain filtering. Advanced editions offer multi-tenant routing, rate limiting, Prometheus metrics, and encrypted backups. Enterprise features include REST APIs, sandbox modes, outbound routing rules, and SIEM forwarding. Compliance tools ensure proof chains.

SMTPPai

SMTP Senpai

SMTP Senpai is MailSenpai's SMTP relay service for the emails your apps, websites, online stores and business software send: order confirmations, invoices, password resets, notifications, reminders and contact forms. Your software keeps writing its emails as before and delivers them through our servers. Three ways to connect: Standard SMTP: server, port 2525 or 587 with STARTTLS, personal username and password. Port 2525 works even where your hosting closes ports 25 and 587. REST API with a key: send, read results and statistics and manage the do-not-contact list. Website forms: an address to put in your form's action, even on a static site, with an anti-bot filter, auto-reply, archive and CSV export. Your domain, your rules: Emails are DKIM-signed on your own domain. We give you the SPF, DKIM and DMARC records to publish and we check them; then a button in the panel sends a test email. You usually go live the same day. See what happens to every email: The sending log is kept for 90 days, line by line: delivered, bounced with the reason, deferred, reported. Search by address, domain or reason. Every month you get a report compared with the previous period. No suspension for crossing a threshold: If you cross a bounce or complaint threshold we don't block you: problem addresses go on the do-not-contact list, don't use up your volume, and we tell you what to fix. Volume under control: Alerts at 50, 80 and 100% of your volume. When it runs out you choose whether to stop or keep sending in blocks of 1,000 emails, up to a spending cap you set. Start on shared, warmed-up addresses or get a dedicated IP from €15/month (included from 150,000 emails a month). Works with: WordPress, WooCommerce, PrestaShop, Supabase, AI-built apps, Laravel, Node.js, business software, printers and anything that sends over SMTP or API. EU servers and real support: Servers and data (log, suppression list, form submissions) are in the European Union. Prices in euro and support from real people in English and Italian. Pricing (VAT excluded): 14-day free trial: €0 today, card required, up to 100 emails a day and a reminder 3 days before the end. Annual plan: 10,000 emails a month €12.90/month, 20,000 €22.90, 50,000 €35.02, 100,000 €43.10. 3-month plan: 10,000 emails at €25.80/month. If you buy straight away without the trial, the first period has a 30-day money-back guarantee.
