Overview

Keap (formerly Infusionsoft) and Sender occupy opposite ends of the email marketing spectrum. Keap is a $299/month all-in-one business platform with CRM, invoicing, and payments. Sender is a $33/month email marketing tool focused on doing the basics well. See our Keap comparison and individual tool pages for more.

The All-in-One Question

The real question isn't which has better email marketing - it's whether you need everything Keap offers. If you're a service business managing client relationships, sending invoices, scheduling appointments, and running email campaigns, Keap consolidates those tools. If you already have a CRM or don't need one, paying $299/month for email marketing makes no sense when Sender does it for $33/month.

Price Per Feature Analysis

At $299/month vs $33/month, Keap costs 9x more than Sender. But Keap includes a CRM, invoicing, payment processing, and appointment scheduling. If you'd otherwise pay for separate CRM ($50-100/month), invoicing ($20-50/month), and scheduling ($15-30/month) tools, Keap's bundled price starts to make more sense. If you only need email campaigns and automation, Sender is the smarter choice. Check our pricing page for transparent per-contact pricing.

Automation Depth

Keap's automation builder can trigger actions across email, CRM, invoicing, and appointments. This cross-functional power is Keap's real strength. Sender's automation handles email sequences and basic behavioral triggers well for the price, but it can't match the complexity of Keap's multi-system workflows. For SaaS-focused automation with Stripe integration, consider Sequenzy.

The Budget Reality

For most small businesses, Sender provides everything needed for effective email marketing. Good templates, solid deliverability, useful automation, and analytics - all at $33/month. The money saved by choosing Sender over Keap ($266/month or $3,192/year) can be invested elsewhere in your business. Only choose Keap if you'll genuinely use the CRM and invoicing features daily.
