Sendy is a self-hosted email marketing application that sends via Amazon SES. Strengths: one-time $69 purchase (no recurring fees), AWS SES pricing ($0.10/1,000 emails), full data ownership, unlimited subscribers. Weaknesses: requires server setup and maintenance, automation is basic, interface is dated, no mobile app, PHP-based architecture. Best for technical users who want maximum cost savings and control. For non-technical users, the setup and maintenance overhead exceeds the cost savings.
Sendy Review 2026: Self-Hosted Email Marketing via AWS SES
Sendy: The One-Time Purchase Email Solution
Sendy is a PHP application you host yourself that sends email through Amazon SES. Pay $69 once, host it on your server, and pay only AWS SES costs for sending. At scale, the cost savings are dramatic.
The tradeoff is clear: you're trading SaaS convenience for self-hosted economics. Sendy handles the fundamentals well but doesn't compete with modern marketing platforms on features.
Pricing (March 2026)
| Component | Cost |
|---|---|
| Sendy license | $69 (one-time) |
| Web hosting | $5-20/month |
| AWS SES | $0.10 per 1,000 emails |
Cost comparison at 50,000 subscribers sending 4x/month:
| Platform | Monthly Cost |
|---|---|
| Sendy + AWS SES | ~$25 |
| EmailOctopus | $77 |
| Mailchimp | $350 |
| ActiveCampaign | $259 |
The economics become more dramatic at scale. 100,000 subscribers on Sendy: ~$45/month. On Mailchimp: $800+/month.
Strengths
One-time purchase. No recurring software fees. The $69 license is permanent. Your only ongoing costs are hosting and sending.
AWS SES economics. At $0.10/1,000 emails, AWS SES is the cheapest reliable sending option available. Sendy leverages this.
Unlimited subscribers. No per-subscriber pricing. 1,000 subscribers costs the same as 1,000,000 (plus sending volume).
Full data ownership. Your data stays on your server. No vendor dependency. Export anytime.
No sending limits. AWS SES sandbox limits apply initially, but production accounts have no hard limits. Scale as needed.
Multiple brands. Manage multiple lists and brands from one installation. Agency-friendly structure.
Weaknesses
Basic automation. Autoresponders exist. Behavioral triggers don't. Multi-step visual workflows don't. Sendy sends emails; it doesn't orchestrate journeys.
Dated interface. The UI is functional but not modern. No drag-and-drop builder. Template options are limited.
Technical maintenance. You're responsible for server updates, security patches, backups, and troubleshooting. This takes time and knowledge.
Limited segmentation. Basic segment by field value. No engagement-based segmentation, no predictive scoring, no behavioral segments.
No advanced analytics. Open rates, clicks, bounces. No cohort analysis, no revenue attribution, no A/B testing.
PHP architecture. If you're not comfortable with PHP hosting, setup and maintenance will frustrate you.
Practitioner note: I recommend Sendy to clients who have technical resources and cost sensitivity. A client with 200,000 subscribers saves $5,000+/month compared to Mailchimp. That savings funds a lot of technical maintenance hours. For clients without technical resources, the hidden cost is their time learning to manage it.
Who Should Use Sendy
Good fit:
- Technical users comfortable with self-hosting
- High-volume senders where cost savings are substantial
- Simple email needs (newsletters, announcements)
- Data-sensitive organizations wanting full control
Bad fit:
- Non-technical users without hosting experience
- Anyone needing marketing automation
- Teams wanting sophisticated analytics
- Organizations without IT resources for maintenance
Sendy vs. Alternatives
| Platform | 50K Subscribers | Automation | Self-Hosted |
|---|---|---|---|
| Sendy | ~$25/mo | Basic | Yes |
| Listmonk | ~$10/mo | Basic | Yes (free) |
| Mautic | ~$15/mo | Advanced | Yes (free) |
| EmailOctopus | $77/mo | Basic | No |
| Mailchimp | $350/mo | Good | No |
Practitioner note: Sendy vs. Listmonk is a common question. Sendy costs $69 but has more features and better support. Listmonk is free but requires more technical comfort. Both use AWS SES. For most users, Sendy's small license fee buys meaningful convenience.
The Bottom Line
Sendy is the right choice for technical teams where cost matters and email needs are straightforward. The economics are compelling — at scale, you're saving thousands monthly compared to SaaS platforms.
The wrong choice is using Sendy when you need features it doesn't have. Marketing automation, behavioral triggers, sophisticated segmentation — Sendy isn't built for these. It's an email sender, not a marketing platform.
If you have technical resources, simple needs, and significant volume, Sendy pays for itself in the first month. If you lack technical resources or need advanced features, the apparent savings become hidden costs.
If you're evaluating self-hosted email options and want guidance on Sendy vs. alternatives like Listmonk or Mautic, schedule a consultation — I'll help you match platform capabilities to your actual needs and technical resources.

Frequently Asked Questions
How much does Sendy cost?
One-time purchase of $69. No recurring software fees. You pay only for hosting (typically $5-20/month) and AWS SES sending costs ($0.10/1,000 emails). At scale, this is dramatically cheaper than SaaS alternatives.
Is Sendy hard to set up?
Moderately technical. Requires web hosting with PHP and MySQL, AWS SES account setup, domain configuration, and cron jobs. If you've set up WordPress, you can set up Sendy. If that sounds foreign, you'll need help.
Is Sendy better than Mailchimp?
Cheaper, yes. Better, depends. Sendy at 50,000 subscribers costs ~$5/month in sending. Mailchimp costs $350/month. But Mailchimp has better automation, templates, and requires no technical setup. Cost vs. convenience.
Does Sendy have good deliverability?
Sendy sends via Amazon SES, which has excellent deliverability when configured correctly. Your deliverability depends on proper AWS SES setup, domain authentication, and list hygiene practices.
What are Sendy's limitations?
Basic automation (autoresponders only), dated interface, no behavioral triggers, no advanced segmentation, requires technical maintenance. It's fundamentally an email-sending tool, not a marketing automation platform.
