AutoSend
AutoSend is a lightweight email platform that combines transactional sending, marketing campaigns and automations behind one REST API, SMTP and an MCP server for AI agents. It bills the volume you send, not the contacts you store.
What is AutoSend?
AutoSend is an email sending platform published by Peerlist Inc., a Delaware company, and positioned as a lightweight alternative to SendGrid. It gathers under one account three products usually sold separately: transactional email, marketing campaigns and automation.
On the transactional side you get a REST API, an SMTP relay, SDKs for Node.js and Next.js, code samples in eight languages, real-time webhooks, and an inbound API that turns incoming messages — body, attachments, headers, SPF, DKIM and DMARC verdicts — into structured JSON so an application can answer in the same thread.
The marketing side adds scheduled campaigns, a Notion-style no-code block editor alongside an HTML editor and React Email support, automated domain warm-up, dynamic segmentation by behavior, geography or contact property, A/B testing of subject lines and content, and real-time campaign analytics. Automation ties the two together, with sequences triggered by a user action, a contact property change or a custom event.
The differentiating angle is agents. AutoSend ships an MCP server, a skill installable in one command and an llms.txt file, and documents eight agent clients — Claude, ChatGPT, Codex, Cursor, Antigravity, Copilot, Windsurf and Lovable — so an assistant can create campaigns, build templates and manage contacts on its own. Zapier and n8n cover the no-code connections.
The infrastructure runs on Amazon SES, with nine publicly disclosed subprocessors including AWS, Cloudflare, Railway, MongoDB, Stripe and PostHog. Deliverability work is explicit: guided SPF, DKIM and DMARC setup, reputation monitoring, dynamic suppression lists and feedback loops. Warmed shared IPs are included, and a dedicated IP becomes available beyond roughly 200,000 to 250,000 emails a month. The homepage advertises publisher figures of 2,720,760 emails over seven days, 97.96% deliverability, 1.87 seconds average time to inbox and a 1.76% bounce rate — none of them audited by a third party.
An account can hold up to 50 isolated projects, each with its own contacts, sending domains and API keys, on a single invoice. The commercial model is the whole argument: you pay for the volume you send, not for the contacts you store, and every tier includes unlimited team members and no daily sending cap.
What it does
- Send transactional email through a REST API or an SMTP relay: one-time passcodes, password resets, order confirmations
- Create and schedule marketing campaigns with a no-code block editor, raw HTML or React Email
- Build triggered automations: welcome series, onboarding sequences, re-engagement flows
- Run the whole email stack from an AI agent through the MCP server
- Receive and parse inbound email as structured JSON, attachments included, and reply in the same thread
- Segment contacts dynamically by behavior, geography or custom properties
- Track opens, clicks, bounces and unsubscribes in real time, in the dashboard or over webhooks
When to use AutoSend / When not to
A quick filter to help you decide if AutoSend is the right fit.
When to use AutoSend
- Startups and SaaS teams that need transactional email — one-time passcodes, password resets, order confirmations — over a REST API or an SMTP relay
- Developers migrating away from SendGrid, Mailgun, Postmark or Resend, who want a familiar API and a smaller invoice
- Teams building with AI agents: the MCP server, the installable skill and the llms.txt file let Claude, ChatGPT, Cursor or Copilot create campaigns, build templates and manage contacts
- Indie hackers and small product teams whose contact lists grow fast, since the price follows the emails sent rather than the contacts stored
- Agencies and multi-product publishers that need isolated projects — separate contacts, sending domains and API keys, up to 50 of them — on a single invoice
When not to use AutoSend
- Anyone operating in an industry banned by the Fair Use Policy: adult content, gambling, unregulated financial services, alcohol, tobacco and vaping, drugs, multi-level marketing and affiliate spam, unlicensed pharmaceuticals, weapons and explosives
- Teams handling protected health information: AutoSend is not a HIPAA covered entity and emails are not end-to-end encrypted by default
- Marketers working from purchased or scraped lists, or with weak list hygiene — complaints above 0.1% or bounces above 4% trigger suspension without warning
- Buyers who need to evaluate a product at zero cost first: there is no free plan and no free trial, and the product is web, API and SMTP only, with no mobile app or browser extension
- Organizations whose procurement requires a published postal address, a named EU representative under GDPR Article 27 or a SOC 2 or ISO 27001 certificate — none of these is published
How to use AutoSend
A typical end-to-end flow, from setup to results.
- Create an account and pick a paid tier: the entry point is USD 1 per month, there is no free plan and no free trial
- Add your sending domain and publish the DNS records: TXT _autosend-verify, TXT autosend._domainkey for DKIM, TXT mail for SPF, MX mail and TXT _dmarc
- Let AutoSend verify authentication: the platform walks you through SPF, DKIM and DMARC and keeps checking them afterwards
- Generate an API key from the dashboard
- Send your first message with POST https://api.autosend.com/v1/mails/send and an Authorization: Bearer YOUR_API_KEY header
- Build the JSON body: from {email, name}, to {email, name}, subject, then either templateId or html and text, plus an optional unsubscribeGroupId
- Prefer no code? Point your application at the SMTP relay, or build campaigns in the block editor without touching the API
- Subscribe a webhook to receive delivery, open, click, bounce and failure events
- For inbound mail, subscribe to inbound events, take the message ID from the payload, then call GET /v1/inbound/messages for the parsed content
- For agents, connect the MCP server to your client (Claude, Cursor, ChatGPT and others) or install the skill with npx skills add autosendhq/skills
Pros & Cons
Pros
- The price follows the volume sent, not the number of contacts stored, so the invoice does not climb as the list grows
- Very low entry point: USD 1 per month for transactional only, USD 5 with marketing included; the publisher advertises around USD 5 per month against roughly USD 49 elsewhere for 2,000 contacts or 10,000 emails
- Transactional and marketing sit in the same product rather than in two separate subscriptions
- Native AI-agent integration: MCP server, installable skill, llms.txt and eight documented agent clients
- Usable with or without code: REST API, SMTP and React Email on one side, a block editor on the other, with an API deliberately designed to feel familiar to developers coming from SendGrid, Mailgun, Postmark or Resend
- Unlimited team members and no daily sending limit on every tier, including the USD 1 plan, and up to 50 isolated projects billed on a single invoice
- The full price grid is published in the open — thirteen tiers, no quote to request — subprocessors are disclosed and a DPA is available on request
Cons
- No free plan and no free trial: you pay before sending a single email, and the publisher states this openly
- Monthly billing only, so no annual commitment discount; refunds are granted only within seven days and only if nothing was sent, with the Hobby tier excluded entirely
- No postal address is published anywhere on the site, email is the only contact channel, and no EU representative under GDPR Article 27 is designated
- No security certification is displayed, neither SOC 2 nor ISO 27001, hosting countries are never named beyond trusted cloud providers with global availability, and the nine disclosed subprocessors are all US-incorporated
- Strict automatic suspension thresholds with no prior warning — complaints above 0.1%, bounces above 4% — and permanent deletion of an account 60 days after the subscription lapses
- The site contradicts itself: email activity retention reads 30 days for Growth and Scale in the comparison table but 60 days in the upper pricing grid, and the marketing grid lists 200,000 contacts at the 10k-email tier against only 150,000 at the 25k tier
- Support is email-only below Growth, there is no mobile app or browser extension, and liability is capped at the amount paid over the preceding six months under Delaware law and mandatory arbitration

Data, GDPR & hosting
A consolidated view of how AutoSend handles your data.
GDPR overview
AutoSend claims full GDPR compliance in its FAQ and lets EU customers select an EU sending region. The privacy policy, updated 1 October 2025, names the legal bases relied on (consent, performance of a contract, legal obligation, legitimate interest) and enumerates data subject rights: access, rectification, erasure, restriction, portability, objection, withdrawal of consent and freedom from automated decision-making, with an express reminder of the right to lodge a complaint with a supervisory authority. Announced response times are 30 days under the GDPR and 45 days under the CCPA. A DPA is available on request and nine subprocessors are publicly listed. Two gaps deserve attention: no EU representative under Article 27 is designated, and no international transfer mechanism, standard contractual clauses included, is mentioned even though all nine subprocessors are US-incorporated. The compliance claim is self-declared, not certified.
Who owns the data?
AutoSend states that it acts as a data processor for everything you send: recipient data, message content and tracking information. The personal information carried inside your emails is treated as your data and processed only to deliver the service on your behalf, and the publisher commits never to sell or rent your distribution lists or your recipients' addresses. You remain responsible for the lawful basis and the consent of the people you email. Contacts, suppression lists and templates can be exported from the dashboard before you leave. Card numbers are never held by AutoSend: payments go through a PCI-DSS compliant third-party processor, Stripe.
Reuse rights
The declared purposes are narrow: delivering the service, improvements and analytics, support and product communication, marketing with consent, fraud and abuse prevention, and legal compliance. AutoSend says it does not access or read the content of your emails except to troubleshoot delivery or as part of automated scanning for spam, phishing and viruses, and that it does not use that content or your recipients' contact information for its own marketing or share it with third parties beyond what delivering the service requires. Connection IP addresses and activity logs are retained to detect unauthorized access. Cookies serve personalization, sessions and analytics, with no third-party advertising, and no automated decision-making producing legal effects happens without human involvement. On your side, reuse is unrestricted: contacts, suppression lists and templates are yours to export and use at any time without asking permission. One silence is worth noting — nothing on the site mentions AI model training on customer data, in either direction.
Data retention & training
Hosting summary
AutoSend names no hosting country. The FAQ says only that its infrastructure is hosted on trusted cloud providers with global availability. The one geographic commitment is optional and concerns sending rather than storage: EU customers can select an EU sending region. The sending infrastructure is built on Amazon SES. Nine subprocessors are publicly disclosed, all US-incorporated: Amazon Web Services (hosting and sending), Cloudflare (application firewall), Railway (web hosting), New Relic (logs and monitoring), Google (analytics, base hosting and email), MongoDB (database), Stripe (payments), PostHog (product analytics) and Slack (internal communication). The publisher, Peerlist Inc., is a Delaware company and the terms designate Delaware law, so US jurisdiction applies by default. Announced security measures are encryption in transit and at rest, regular audits and vulnerability assessments, access controls and authentication, and physically secured data centers. No certification is displayed, neither SOC 2 nor ISO 27001, and no international transfer mechanism such as standard contractual clauses is mentioned.

Things to keep in mind
Risks and trade-offs to weigh before adopting AutoSend.
- Sending can be suspended automatically and without prior warning if complaints exceed 0.1% or bounces exceed 4%: a single badly sourced list is enough to cut off your email
- An account without an active subscription is permanently deleted 60 days after the subscription lapses, after reminders on days 30, 45 and 53; the publisher states the deletion is irreversible and that nothing can be recovered, restored or reproduced
- Contractual penalties reach USD 500 per phishing or fraudulent email, plus recovery of delisting costs, and credits and subscription fees are forfeited without refund in cases of serious abuse
- No refund once the first email of a quota has been sent, and otherwise only within seven days; total liability is capped at what you paid over the preceding six months, under Delaware law and mandatory arbitration
- No postal address is published, so email is the only way to reach the publisher — a real constraint for any formal notice or dispute
- The site announces 30 days of email activity retention for Growth and Scale in its comparison table but 60 days in the upper pricing grid: confirm what you actually get before relying on those logs for support, auditing or proof of delivery
- AutoSend is not a HIPAA covered entity and emails are not end-to-end encrypted by default, while content passes through automated abuse scanning: sensitive material does not belong in this channel
Setup & Integrations
Technical difficulty
Two clearly separate paths. Marketing requires no code: campaigns, block editor and automations are built for non-technical users. Transactional sending is developer work — a single POST to /v1/mails/send with a Bearer API key, SDKs for Node.js and Next.js, samples in eight languages. The shared hurdle is DNS: five records on the sending domain (_autosend-verify, DKIM, SPF, MX, DMARC), with guided setup and continuous checking. Agents add an MCP server or a one-command skill install, and large teams are offered individual onboarding. Overall: easy for marketers, straightforward for developers, moderately fiddly for anyone who has never edited a DNS zone.

Should you pick AutoSend?
AutoSend's promise is easy to check: you pay for the emails you send, not for the contacts you store. For startups, SaaS teams, indie hackers and developers — and for teams wiring email into AI agents through the MCP server — that single decision removes the cost cliff most email platforms build in as a list grows. Transactional and marketing live in the same product, the API is deliberately familiar to anyone migrating from SendGrid, Mailgun, Postmark or Resend, and the whole grid is public: thirteen tiers, from USD 1 to USD 1,290 per month, with no quote to request.
The reservations are real. There is no free plan and no free trial, so evaluation starts with a card. No postal address appears anywhere on the site, email is the only channel, and no EU representative under Article 27 is designated. No security certification is displayed, and hosting countries are never named: an EU sending region can be selected, but the nine disclosed subprocessors are all US-incorporated. The site also contradicts itself on activity retention, 30 days against 60, and on marketing contact quotas — a small but telling sign of a young product.
Two operational rules deserve attention before migrating an existing list: complaints above 0.1% or bounces above 4% trigger suspension without warning, and an account without an active subscription is irreversibly deleted 60 days after the subscription lapses.
The publisher is identified, Peerlist Inc., a Delaware company; subprocessors are disclosed and a DPA is available on request. For a small team sending real volume on a tight budget, AutoSend is a serious option. For a procurement process that requires certifications, a legal address and a named EU representative, it is not there yet.
