Overview
SendX and EmailOctopus are both budget email platforms, but with different approaches. EmailOctopus uses Amazon SES infrastructure for ultra-low pricing. SendX offers unlimited sends with more features included.
See our SendX comparison and EmailOctopus comparison for individual deep dives.
The Price Reality
At 10,000 subscribers:
- EmailOctopus: $36/month
- SendX: $59.99/month
EmailOctopus is 40% cheaper. At 50,000 subscribers, EmailOctopus is $87/mo vs SendX's ~$149/mo. The gap is significant at scale.
Plus, EmailOctopus offers 2,500 subscribers and 10,000 emails free. SendX only has a 14-day trial.
EmailOctopus's Cost Advantage
Amazon SES Integration
EmailOctopus lets you connect your own Amazon SES account. With SES, sending costs drop to ~$0.10 per 1,000 emails. For high-volume senders, this is dramatically cheaper than any competitor.
Generous Free Tier
2,500 subscribers and 10,000 emails monthly - free forever. You can run a small newsletter business without paying. This is genuine bootstrapping runway.
Simple Feature Set
EmailOctopus doesn't try to be everything. Basic email, basic automation, basic landing pages. Simplicity keeps costs down.
SendX's Value Proposition
Unlimited Sends
SendX removes send limits entirely. Email your list daily without worrying about caps. For high-frequency senders, this predictability matters.
Better Automation
SendX has visual automation workflows. EmailOctopus automation is more basic - sequences and simple triggers. For complex subscriber journeys, SendX offers more.
Browser Push
SendX includes web push notifications. Additional channel for engagement beyond email. EmailOctopus is email only.
More Templates
64 templates vs EmailOctopus's 30+. More starting points for email design.
For SaaS Companies
Neither platform is built for subscription businesses:
- No native Stripe integration
- No MRR or churn segmentation
- No subscription lifecycle triggers
For SaaS-specific features, Sequenzy offers Stripe integration and AI sequences at $49/month for 120k emails (unlimited subscribers).
The Verdict
Choose EmailOctopus for lowest possible cost, especially with Amazon SES integration. The free tier and low paid pricing are hard to beat for simple email needs.
Choose SendX if you need unlimited sends, browser push, or more sophisticated automation. Higher price but more features.
Choose Sequenzy if you run a SaaS and need subscription-aware automation with native Stripe integration.

Budget Email Marketing Showdown
Both SendX and EmailOctopus target budget-conscious businesses but with different strategies. SendX offers more features at a moderate price. EmailOctopus offers fewer features at an aggressively low price. The right choice depends on whether you need the extra features.
SendX's email heatmaps, unlimited sends, and better automation justify the premium for businesses that actively optimize their email performance. EmailOctopus at a fraction of the cost handles basic newsletters and campaigns without the optimization tools.
For businesses where email marketing is a support function rather than a primary growth channel, EmailOctopus saves money without meaningful capability loss. For businesses actively optimizing email as a revenue driver, SendX's additional features provide useful tools.
Amazon SES Advantage
EmailOctopus's integration with Amazon SES provides enterprise-grade deliverability at extremely low per-email costs. This infrastructure advantage means small businesses get the same sending reliability as major enterprises.
SendX uses its own sending infrastructure which is adequate but less proven at scale. For businesses where inbox placement directly impacts revenue, EmailOctopus's SES backbone provides a meaningful deliverability advantage.

Best Fit by Budget Newsletter Workflow

Pricing reality

SendX should be evaluated on whether its budget or unlimited-send positioning holds at your actual list size and campaign frequency. EmailOctopus's real cost depends on whether the team needs simple low-cost email marketing.
Sequenzy is not a generic newsletter-blast replacement. It is a better value only when the buying job is lifecycle automation, transactional email, and SaaS or commerce events.
