Best Fit by Amazon SES Cost Control
Best Sendy alternative for managed SaaS email
Sequenzy is the better Sendy alternative when the team wants managed marketing, transactional email, Stripe-triggered automation, AI-generated sequences, and support without maintaining a self-hosted app. Start with Stripe integration, transactional emails, and SaaS onboarding templates.
Best platform for rock-bottom Amazon SES sending
Sendy is the better fit when the buyer wants a one-time license and very low Amazon SES sending costs. Compare Amazon SES, Listmonk, and the pay-per-email platform guide if price per send is the main job.
Best Sendy alternative for SaaS automation
Sequenzy is stronger when email should branch by trial state, billing events, usage behavior, and churn risk. SaaS trial conversion templates are a better fit than simple broadcast software.
Best setup when SES is already in place
Keep Sendy for low-cost newsletters if it already works. Add Sequenzy when the company needs transactional, product-led, and billing-aware lifecycle email.
These Are Different Approaches to Email
Let's be clear upfront: Sendy and Sequenzy solve email marketing with different philosophies.
Sendy is $69 one-time, self-hosted, locked to Amazon SES. Extremely cheap at scale.
Sequenzy is managed SaaS. We handle infrastructure, you focus on marketing.
Neither is "better" - they serve different priorities and team capabilities.
When should you choose Sequenzy?
Sendy vs Sequenzy Fit Table
| Priority | Better fit | Why |
|---|---|---|
| Lowest possible high-volume sending cost | Sendy | Amazon SES plus one-time software pricing is extremely cheap. |
| Managed SaaS lifecycle email | Sequenzy | Stripe sync, AI sequences, and deliverability are handled for you. |
| Multi-brand agency newsletters | Sendy | One installation can manage many brands cheaply. |
| Transactional plus marketing email | Sequenzy | Sendy is mainly newsletter/autoresponder software. |
| Non-technical setup | Sequenzy | Sendy needs PHP, MySQL, hosting, SES, and cron configuration. |
1. You Don't Want to Manage Infrastructure
Sendy requires PHP, MySQL, web server setup, and Amazon SES configuration including domain verification and sending limit increases. If you'd rather focus on building your SaaS than managing email infrastructure, Sequenzy is fully managed.
2. You Need SaaS-Specific Features
Sequenzy is purpose-built for SaaS with Stripe integration, trial expiry sequences, churn prevention, and MRR tracking. Sendy is a general newsletter tool - you'd need custom development for SaaS-specific functionality.
3. You Want AI-Generated Content
Describe what you want ("a 5-email onboarding sequence for a project management SaaS") and our AI generates the emails. Sendy has no content creation features - it efficiently sends what you write.
4. You Want Unified Transactional + Marketing
Sequenzy handles both transactional emails (password resets, receipts) and marketing campaigns in one platform. Sendy is primarily newsletter-focused - transactional typically uses SES directly.
5. You Don't Want Amazon SES Lock-in
Sendy only works with Amazon SES. If you want flexibility to switch email providers or don't want to manage AWS accounts, Sequenzy handles delivery without provider lock-in.
When should you stick with Sendy?
1. Cost Is Your Top Priority
Sendy is genuinely the cheapest option for high-volume email. After the $69 one-time payment, you pay only Amazon SES costs: $0.10 per 1,000 emails. Send 100,000 emails monthly for ~$10. That's unbeatable at scale.
2. You Prefer One-Time Payment
No monthly subscription eating into your budget. Pay once, use forever. Your only ongoing costs are hosting (~$5-20/mo) and SES usage. For cost-conscious founders, this model is compelling.
3. You Want Self-Hosted Data Control
Your data stays on your servers. No third-party has access. For privacy-conscious companies or those with strict compliance requirements, self-hosting offers peace of mind that SaaS can't match.
4. You Run Multiple Brands or Clients
Sendy handles unlimited brands with a single installation. Good for agencies or portfolios. Each brand has separate lists, campaigns, and reporting. One $69 license covers everything.
5. You're Comfortable with PHP/MySQL
If you're technical and already run web applications, Sendy setup is straightforward. The stack (PHP + MySQL) is familiar and well-documented.
Honest Limitations of Sequenzy
- More expensive at scale: $99/mo for 120k emails vs Sendy's ~$10-15/month after one-time cost.
- Subscription model: Monthly payment vs one-time purchase.
- No self-hosting: Managed SaaS only.
- You don't own infrastructure: Your data is on our servers.
- Newer platform: Less history than Sendy's 10+ years.
Honest Limitations of Sendy
- Requires DevOps: PHP, MySQL, web server, Amazon SES setup and maintenance.
- Amazon SES lock-in: Cannot use Mailgun, SendGrid, or other providers.
- No AI features: No content generation or AI assistance.
- Basic automation: Autoresponders only, no visual workflow builder.
- Dated interface: Functional but not modern.
- Solo developer support: Response times vary, no enterprise support.
- No native integrations: No Stripe, Zapier, or pre-built connectors without third-party help.
The Real Cost Comparison
At 10,000 subscribers, sending 100,000 emails/month:
| Cost or responsibility | Sendy + Amazon SES | Sequenzy |
|---|---|---|
| Software | $69 one-time | Included in subscription |
| Sending provider | Amazon SES only | Managed by Sequenzy |
| Hosting | Your VPS | Included |
| Maintenance | You handle updates, backups, cron, and security | Managed |
| SaaS lifecycle features | Custom development | Native Stripe-focused workflows |
Sendy self-hosted:
- One-time: $69
- VPS hosting: ~$10/month
- Amazon SES (100k emails): ~$10/month
- Total year 1: $69 + $240 = $309
- Total year 2+: ~$240/year
Sequenzy managed:
- Everything included: from $19/mo for 15k emails
- Total year 1: $588
- Total year 2: $588
Sendy is significantly cheaper at scale. The question is whether AI content generation, Stripe integration, and zero DevOps are worth the premium.
A Note on Amazon SES Setup
If you go with Sendy, you'll need to:
- Create AWS account and set up Amazon SES
- Verify your domain with DNS records
- Request production access (SES starts in sandbox mode with limited sending)
- Set up bounce/complaint handling (Sendy configures SNS for this)
- Monitor sending reputation - SES can suspend accounts for poor reputation
This is straightforward for developers but represents overhead compared to managed platforms.
Sendy's Sweet Spot
Sendy is ideal for:
- Agencies managing multiple client brands
- High-volume senders where per-email cost matters
- Developers comfortable with self-hosting
- Budget-conscious founders who prioritize cost over features
- Newsletter publishers with straightforward needs
If you're sending 500k+ emails monthly, the cost difference becomes substantial. Sendy + SES at that volume is ~$50/month. Managed platforms charge significantly more.
Self-Hosting Considerations
If you go with Sendy, you'll need:
| Requirement | Why it matters | Risk if skipped |
|---|---|---|
| SES production access | Amazon starts accounts in sandbox mode | Campaigns cannot send normally until approved. |
| Bounce and complaint handling | Protects sender reputation and cleans lists | Bad addresses keep receiving mail. |
| Cron jobs | Scheduled campaigns and autoresponders depend on them | Automations may not run. |
| Server updates | PHP apps need maintenance | Security and uptime become your responsibility. |
- Server: $5-20/mo VPS from DigitalOcean, Hetzner, or similar
- PHP: 7.4+ with required extensions
- MySQL/MariaDB: Database for subscriber storage
- Web Server: Apache or Nginx
- Cron Job: For scheduled campaigns and autoresponders
- SSL Certificate: Required for secure signup forms
Most developers can set this up in 2-4 hours. Docker setups exist to simplify deployment.
