for SSO & API
Google SSO, API access, and audit logs included from day one — not gated behind a $499/mo "Professional" plan like the others.
One platform

Who it's for
From solo developers to multi-client agencies, SendAuto scales with your communication needs.
Send transactional emails, product notifications, and onboarding sequences. Track every open and click without a separate tool.
Abandoned cart emails, order confirmations, and promotional blasts to your full customer list. CAN-SPAM compliant by default.
Manage multiple client tenants from one account. Each client gets isolated data, separate domains, and independent sending.
Design campaigns with the template editor, segment your audience with contact lists, and schedule sends for optimal delivery times.
Drop-in REST API with scoped keys. Send transactional email and SMS via code, and track delivery events in real time.
Audit logs, approval workflows, and document acknowledgement tracking for compliance-heavy sectors like finance and healthcare.
Security & Compliance
Built on AWS SES with per-tenant reputation isolation, real-time abuse prevention, enforced authentication, and an immutable evidence ledger — controls that are deployed, not just described.
New tenants can only send transactional email — verification, resets, alerts, receipts. Marketing sending is gated behind admin business verification and cannot be self-service enabled.
Native SES Tenant Management gives every tenant its own sending reputation metrics, configuration set, and automated pause policy. SES-native enforcement acts independently of platform monitoring.
The SES webhook triggers a pause check on every bounce and complaint event — sub-second response. Tenants exceeding 5% bounce or 0.1% complaint rates are suspended immediately, not hourly.
Every sender domain must pass DNS authentication before sending. DMARC records are verified automatically. No unauthenticated email leaves the platform.
Marketing email requires explicit double opt-in. Purchased, scraped, and harvested lists are prohibited and blocked server-side. Consent records are immutable and auditable.
Bounces, complaints, unsubscribes, and spam-trap hits create protected suppression records that tenants cannot remove. Every send path checks suppression before delivery.

Built for compliance
Every control below is deployed in production and enforced server-side. No claim here depends on a tenant setting a flag or reading a policy — the platform refuses the action if the check fails.
New tenants can only send transactional email — account verification, password resets, security alerts, receipts, and workflow notices. Marketing sending requires admin business verification.
Marketing email requires a confirmed double opt-in. Manual and imported contacts default to Pending Verification and cannot receive marketing email until the recipient confirms via a single-use expiring token.
Hard bounces, complaints, unsubscribes, and spam-trap hits create protected suppression records that tenants cannot remove. Every send path checks suppression before submitting to AWS SES.
The SES webhook itself triggers a pause check on every bounce and complaint event — sub-second response, not hourly. Tenants exceeding 5% bounce or 0.1% complaint rates are suspended immediately.
Every compliance-sensitive action — opt-in confirmation, suppression creation, tenant pause, SES status sync — is logged to an append-only audit trail with before/after state and actor tracking.
Each tenant is a first-class AWS SES tenant entity with isolated reputation metrics, per-tenant configuration sets, and automated pause policies. SES-native enforcement acts independently of platform monitoring.

FAQ
Everything you need to know about the platform.
We use AWS SES as our email infrastructure — the same service Netflix and Airbnb use. SES costs $0.16 per 1,000 emails on the Essentials plan. Competitors mark that up 5-10× and charge you for it. We pass the SES savings directly to you with a modest margin, so you get enterprise deliverability at a fraction of the cost.
The Free plan is free forever and includes up to 500 emails per month, one sending domain, and full access to the unified inbox and document workflows. No credit card required to sign up. Upgrade only when you need more volume.
No. SendAuto manages the AWS SES infrastructure for you. You simply verify your sending domain by adding the DKIM, SPF, and DMARC DNS records we auto-generate, and you are ready to send. No AWS account, no console, no IAM policies to manage.
Yes. Import your existing contact lists via CSV, re-create your email templates in our editor, and update your DNS records. Most teams complete migration in under an hour. Your sending reputation carries over once your domain is verified.
Every record in the platform is scoped to your tenant via row-level security. Your data, contacts, campaigns, and messages are completely isolated from other organizations. Agencies can manage multiple client tenants from a single account with zero data bleed.
You will be notified before you reach your limit. You can upgrade your plan or top up your wallet with pay-as-you-go credits at $0.40 per 1,000 emails — 60% cheaper than Brevo's pay-as-you-go rate. Emails never stop sending unexpectedly.
Yes. Every plan — including Free — includes REST API access with scoped API keys. You can send transactional emails, manage contacts, create campaigns, and retrieve analytics programmatically. No $499/mo "Professional" plan required like with Brevo.
Yes. We enforce DKIM, SPF, and DMARC authentication on every domain, inject CAN-SPAM-compliant unsubscribe footers, and monitor bounce and complaint rates automatically. You get the same AWS SES deliverability that powers Netflix, Airbnb, and Stripe — not a third-rate shared IP.
