Overview
Sender and ConvertKit serve completely different markets. Sender is built for e-commerce businesses with Shopify/WooCommerce integrations and SMS marketing. ConvertKit is built for creators with paid newsletters and monetization tools.
Choose based on your business type, not just features.
The Core Difference
Sender is e-commerce focused. Rich templates, product integrations, abandoned cart automation, SMS marketing. It helps stores sell more products through email and text.
ConvertKit is creator focused. Simple text emails, paid newsletters, tip jars, digital products. It helps writers, podcasters, and YouTubers build and monetize their audiences.
Pricing: ~$45 vs $66 at 10K
At 10,000 subscribers, Sender costs around $45/month and ConvertKit costs $66/month. Sender is about 30% cheaper.
The free tiers have different trade-offs. ConvertKit offers 10,000 free subscribers but only for basic sending (no automation). Sender offers 2,500 free subscribers with 15,000 emails and basic automation included.
Where Sender Wins
Pricing: 30% cheaper at the 10k subscriber tier.
E-commerce: Deep Shopify and WooCommerce integrations with abandoned cart and product automations.
SMS Marketing: Built-in SMS capabilities. ConvertKit has no SMS.
Templates: 1600+ rich email templates. ConvertKit intentionally keeps emails minimal.
A/B Testing: Full A/B testing capabilities. ConvertKit only tests subject lines.
Where ConvertKit Wins
Paid Newsletters: Built-in paid subscription features for monetizing content.
Creator Tools: Tip jars, digital product sales, creator recommendations network.
Free Subscriber Limit: 10,000 free subscribers (though limited features) vs 2,500.
Simplicity: Tag-only organization without complex lists. Simpler for non-technical users.
Landing Pages: Better landing page builder for capturing leads.
Different Philosophies
Sender believes in rich, designed emails with lots of templates. ConvertKit believes simple, text-focused emails perform better and feel more personal.
Neither is wrong - they serve different audiences. E-commerce customers expect polished promotional emails. Newsletter readers often prefer simple, authentic content.
For SaaS Companies
Neither Sender nor ConvertKit is built for SaaS. Sender is for e-commerce, ConvertKit is for creators.
If you're running a SaaS company and want automation that triggers based on Stripe events, consider Sequenzy at $49/month. SaaS-specific features that neither platform offers.
