You're publishing on Substack, building an audience, and now you want a secondary email list—maybe for a paid product, a course launch, or a separate newsletter with different monetization. You need to know which tool gets that list up and running fastest without bleeding budget or forcing you to learn enterprise automation you'll never use.

This comparison cuts through the feature bloat to answer one question: should a Substack writer pick Kit or Moosend for a secondary product list? We'll cover free plan limits, creator-focused features, real pricing after recent changes, and the honest downsides each tool tries to hide in the fine print.

By the end, you'll know which tool fits your situation—or when to skip both and stick with what you already have.

Quick Comparison Table

Kit: The Creator-First Tool That Just Got More Expensive

Kit raised its Creator plan from $29 to $39/month in September 2025—a 34% jump and the first price increase in 12 years. For 1,000 subscribers, you're now paying $468 annually instead of $348. That stings, especially if you're just starting to monetize.

What makes Kit worth considering anyway? The free Newsletter plan expanded to 10,000 subscribers in 2025, up from 1,000. You get unlimited email broadcasts and one automation sequence—enough to run a basic welcome series or product launch funnel. For Substack writers testing a secondary list (a course waitlist, a paid community, a Gumroad product), that free tier buys you months of validation before you pay a cent.

The creator monetization features are where Kit separates from traditional email tools. Native Stripe integration means you can sell paid newsletters, digital products, or accept tips directly through Kit—no third-party landing page required. Gumroad integration is built-in. If you're launching a $47 course or a $9/month membership, Kit handles the payment flow and subscriber tagging automatically.

Who it fits: Substack writers who plan to monetize a secondary list within 6-12 months. If you're building a waitlist for a paid course, testing a second newsletter with sponsorships, or selling digital products alongside your Substack, Kit's creator tools justify the $39/month once you cross 10,000 free subscribers or need more than one automation.

Real downsides: No live chat support on the Creator plan—email only, with a 24-hour average response time. Live chat requires the Creator Pro tier at $79/month. The September 2025 price hike also signals Kit may increase prices again; 12 years of stability ended, and there's no promise the next increase won't come sooner. The interface is clean but opinionated—Kit pushes its "Creator" workflow hard, which feels patronizing if you just want a simple broadcast tool.

Pricing: Free for up to 10,000 subscribers (unlimited sends, 1 automation). Creator plan at $39/month for 1,000 subscribers, scaling up as your list grows. Creator Pro at $79/month adds live chat, advanced automations, and subscriber scoring. 30-day money-back guarantee on paid plans.

Moosend: Budget E-Commerce Tool Owned by Constant Contact

Moosend was acquired by Constant Contact in June 2025. As of mid-2026, it still operates as a standalone product with no announced changes to pricing or features—but the long-term roadmap is uncertain. If Constant Contact decides to consolidate products or sunset Moosend's brand, your secondary list could be migrated into a different platform without your input.

What Moosend does well: It's cheap. The Pro plan starts at $9/month for 500 contacts, $16/month for 1,000 contacts—less than half of Kit's entry price. The email builder is drag-and-drop simple, templates are modern, and automation workflows are visual and intuitive. If you're selling physical products or running a WooCommerce store alongside your Substack, Moosend's native e-commerce integrations (WooCommerce, Magento, OpenCart) beat Kit's creator-focused toolset.

The catch: Moosend has no permanent free plan—only a 30-day trial for up to 1,000 contacts. After that, you pay or lose access. For Substack writers testing a secondary list idea, that trial window forces a decision before you've validated demand. Kit's 10,000-subscriber free plan gives you months or years to experiment; Moosend gives you 30 days.

Who it fits: Substack writers who already know they need a paid tool and want the lowest monthly cost. If you're launching a product shop (Etsy, WooCommerce, Gumroad) alongside your newsletter and need e-commerce automation—abandoned cart emails, purchase follow-ups, product recommendation sequences—Moosend's $16/month for 1,000 contacts is half what you'd pay for Kit or Beehiiv.

Real downsides: Multiple Trustpilot complaints about auto-renewal charges without prior notice and refused refunds. Moosend's billing is non-refundable after the trial ends, and several users report being charged for annual renewals without email reminders, then denied refunds. Live chat support is Monday-Friday only (not 24/7), and phone support doesn't exist on any plan. Account managers are reserved for the custom-priced Moosend+ tier.

The bigger risk: Moosend has zero creator monetization features. No paid newsletter integration, no tip jar, no Stripe checkout. If your secondary list is for a paid product, you'll need to bolt on Gumroad, Stripe, or a landing page builder separately. Kit handles that natively.

Pricing: 30-day free trial (1,000 contacts). Pro plan at $9/month (500 contacts), $16/month (1,000 contacts), scaling up. No refunds after trial ends. No permanent free plan.

The Honest Verdict: When Each Tool Makes Sense

Pick Kit if: - You're monetizing the secondary list within a year (paid newsletter, course, digital products) - You want to test the idea for free with up to 10,000 subscribers before committing budget - You value creator-focused integrations (Stripe, Gumroad, Teachable) over e-commerce automation - You're willing to pay $39/month once you need more than one automation or cross 10k subscribers

Pick Moosend if: - You already know you need a paid tool and want the lowest monthly cost ($16/mo for 1,000 contacts) - You're selling physical products or running an e-commerce store (WooCommerce, Magento) alongside Substack - You're comfortable managing monetization separately (Gumroad, Stripe checkout, landing pages) - You can validate your list idea within the 30-day trial window

Skip both and use Substack's native tools if: - Your "secondary list" is just another newsletter—Substack already handles unlimited subscribers for free - You're not selling products outside Substack's ecosystem (paid subscriptions work fine natively) - You don't need complex automation (welcome sequences, product funnels, segmentation)

Skip both and use Beehiiv if: - You want a free plan with automation (up to 2,500 subscribers) and don't mind switching newsletter platforms entirely - You're building a media brand with ad network monetization, not just product sales

Skip both and stick with Mailchimp or Brevo if: - You already use one of these tools for another project and can add a secondary audience/list for free - You're under 500 subscribers and Mailchimp's free plan (500 contacts, basic automations) covers your needs

Final Recommendation: Kit's Free Plan Wins for Substack Writers

For most Substack writers building a secondary product list, Kit's expanded free plan (10,000 subscribers, unlimited sends, 1 automation) is the fastest path to validation. You can test a course waitlist, a paid community, or a Gumroad product launch for months—maybe years—without spending a dollar. When you're ready to monetize, the native Stripe and Gumroad integrations mean you're not duct-taping together landing pages and payment processors.

Moosend's $16/month for 1,000 contacts looks cheaper than Kit's $39/month, but the 30-day trial-only model forces you to pay before you've proven demand. Unless you're already running an e-commerce store with WooCommerce and need those specific integrations, the budget savings don't offset the lack of a long-term free option or creator monetization tools.

The real decision point: if you're still figuring out what to sell on your secondary list, start with Kit's free plan. If you already have a product, a shop, and 1,000+ contacts ready to import, Moosend's $16/month is half the cost—just read the refund policy twice and set a calendar reminder before your trial ends.
