Question 1

What is SendMesh?

Accepted Answer

SendMesh is an API-first email infrastructure platform built on AWS SES. It provides a modern REST API, deliverability dashboard, and compliance automation for sending transactional and marketing emails at scale, at a fraction of the cost of competitors like SendGrid or Mailchimp.

Question 2

How is SendMesh different from SendGrid?

Accepted Answer

SendMesh is built directly on AWS SES, which means you get SES-level pricing (10x cheaper at scale) with a developer-friendly API, real-time analytics dashboard, automatic bounce/complaint handling, and built-in compliance. We pass the infrastructure savings directly to you instead of marking up SES costs.

Question 3

What regions do you support?

Accepted Answer

SendMesh currently operates from AWS US East (N. Virginia) and EU West (Ireland) regions. Emails are routed through the optimal SES endpoint based on your account configuration. We plan to add Asia Pacific endpoints in the future.

Question 4

Is there a free tier?

Accepted Answer

Yes. The Free plan includes 1,000 emails per month at no cost, with access to all core features including the API, dashboard analytics, email validation, and community support. No credit card required to get started.

Question 5

How does billing work?

Accepted Answer

SendMesh uses monthly subscription billing via Stripe. Each plan includes a set number of emails per month. You are billed at the start of each billing cycle. Annual plans receive a 17% discount. Usage resets at the start of each billing period.

Question 6

What happens if I exceed my quota?

Accepted Answer

When you approach your monthly email limit, we send alerts at 80% and 95% usage. If you exceed your plan limit, overage emails are charged at your plan's per-email rate. You can set hard limits in the dashboard to prevent overage charges if preferred.

Question 7

Can I upgrade or downgrade anytime?

Accepted Answer

Yes. You can change your plan at any time from the billing dashboard. Upgrades take effect immediately with prorated charges. Downgrades take effect at the start of the next billing cycle. No long-term contracts or cancellation fees.

Question 8

What email providers does SendMesh support?

Accepted Answer

SendMesh is powered exclusively by AWS SES (Simple Email Service), which provides industry-leading deliverability and reliability. All emails are sent through SES with SendMesh handling queue management, retry logic, bounce processing, and compliance enforcement on top.

Question 9

How do I verify my domain?

Accepted Answer

Add your domain in the dashboard, then configure the provided DKIM, SPF, and DMARC DNS records with your DNS provider. SendMesh checks DNS propagation automatically and verifies your domain. Most domains are verified within 5-60 minutes. See the Getting Started guide for detailed instructions.

Question 10

What are the rate limits?

Accepted Answer

Rate limits depend on your plan: Free (10 req/min), Starter (60 req/min), Growth (300 req/min), Pro (600 req/min), Scale (1,200 req/min), Enterprise (custom). Limits are per account and tracked via X-RateLimit headers in every response. Batch endpoints count as one request regardless of recipient count.

Question 11

Do you support attachments?

Accepted Answer

Yes. The POST /v1/emails/send endpoint supports file attachments up to 10MB total per email. Attachments are passed as base64-encoded content in the request body. Supported formats include PDF, images, CSV, and common document types. Executable files (.exe, .bat) are blocked for security.

Question 12

What webhook events are available?

Accepted Answer

SendMesh fires webhooks for: email.queued, email.sent, email.delivered, email.bounced, email.complained, email.opened, email.clicked, email.unsubscribed, and email.failed. All payloads include an HMAC-SHA256 signature for verification. Failed deliveries are retried up to 5 times with exponential backoff.

Question 13

What delivery rate can I expect?

Accepted Answer

SendMesh customers typically see 99%+ delivery rates when following best practices (verified domain, proper authentication, clean lists). The platform automatically handles suppression lists, bounce processing, and complaint feedback loops to maintain your sender reputation.

Question 14

How do you handle bounces?

Accepted Answer

Hard bounces (invalid addresses) are automatically added to your account suppression list so the same address is never attempted again. Soft bounces (temporary failures like full mailboxes) are retried up to 3 times over 24 hours. Bounce rates are tracked in real-time on your dashboard with alerts if you approach the 3% threshold.

Question 15

How do you handle complaints?

Accepted Answer

When a recipient marks your email as spam, the complaint is processed via SES feedback loops within seconds. The address is immediately added to your suppression list. If your complaint rate exceeds 0.1%, you receive a warning. At 0.3%, sending may be automatically paused to protect your reputation.

Question 16

What is the warm-up process?

Accepted Answer

If you use a dedicated IP, SendMesh provides an automated warm-up schedule that gradually increases sending volume over 4-6 weeks. The system distributes emails between your dedicated IP and the shared pool during warm-up to ensure high deliverability from day one. Growth plan and above can add dedicated IPs.

Question 17

Is my data encrypted?

Accepted Answer

Yes. All data is encrypted in transit (TLS 1.2+) and at rest (AES-256-GCM). Email content, contact data, and webhook secrets are encrypted at the field level. Database storage uses AWS RDS encryption, and object storage uses SSE-S3. Encryption keys are managed by AWS KMS with annual rotation.

Question 18

Are you GDPR compliant?

Accepted Answer

Yes. SendMesh provides built-in GDPR compliance tools including consent tracking, right-to-erasure processing (within 72 hours), data export API for portability requests, and configurable data retention periods. We also offer a Data Processing Agreement (DPA) for EU customers.

Question 19

How are API keys stored?

Accepted Answer

API secret keys are hashed with bcrypt (12+ rounds) before storage. The plaintext key is shown exactly once at creation time and is never stored or recoverable. If you lose a key, you must revoke it and generate a new one. All key usage is logged with timestamps and IP addresses for audit purposes.

Question 20

Do you support 2FA?

Accepted Answer

Yes. Two-factor authentication is available for all dashboard accounts via TOTP (authenticator app) or SMS. 2FA is required by default on Scale and Enterprise plans. We strongly recommend enabling it on all accounts to protect API key management and account settings.
