Rekko vs ProfitWell Retain (Paddle Retain): Independent Tool vs Platform Feature

Rekko vs ProfitWell Retain: What Changed After the Paddle Acquisition

ProfitWell built a reputation as a free analytics tool with a paid recovery product called Retain. In 2022, Paddle acquired ProfitWell, and the product has been gradually integrated into the Paddle ecosystem. If you're evaluating Retain today, you're really evaluating a Paddle product, and that changes the calculus.

Rekko is an independent, Stripe-focused recovery tool with flat-rate pricing. No platform lock-in, no ecosystem requirements.

The Core Difference

Rekko is a standalone SaaS that connects to your Stripe account and runs automated email + SMS recovery sequences. You own the relationship with your payment processor. Rekko earns your business every month on a flat fee.

ProfitWell Retain (now Paddle Retain) uses machine learning to optimize retry timing and sends recovery emails. It was once a standalone product with a pay-for-performance model. Under Paddle, its future as an independent tool for non-Paddle customers is less certain.

Feature Comparison

The Paddle Acquisition Factor

This is important context. Before the acquisition, ProfitWell Retain was a straightforward product: connect your billing system, let Retain optimize retries and send recovery emails, pay based on what it recovered. Simple value proposition.

Post-acquisition, things are shifting:

Ecosystem pressure. Paddle is a merchant of record platform. Their business model works best when you use Paddle for everything: billing, payments, tax, and recovery. Retain as a standalone product for Stripe users may not be Paddle's long-term priority.

Product direction. New features and improvements tend to favor the integrated Paddle experience. If you're a Stripe user relying on Retain, you may not get the same level of attention as Paddle customers.

Pricing changes. The original pay-for-performance model is being restructured. Some users report being pushed toward Paddle's bundled offerings.

Uncertainty. Acquisitions create uncertainty. Will Retain continue to exist as a standalone product? Will pricing stay stable? For a tool that handles revenue recovery, predictability matters.

None of this means Retain stopped working overnight. It still recovers payments. But the trajectory favors Paddle customers, not independent Stripe users.

Smart Retries: Where Retain Shines

Credit where it's due: ProfitWell Retain's retry optimization is genuinely good. Their machine learning model analyzes payment failure patterns and retries at times when the charge is most likely to succeed, factoring in things like time of day, day of week, and failure code.

This "silent recovery" happens without any customer-facing communication. The payment just goes through on a retry, and the customer never knows there was a problem. ProfitWell has published data showing their retries alone recover a meaningful percentage of failed payments.

Rekko relies on Stripe's native Smart Retries for this layer. Stripe's retry logic is solid but not as specialized as what Retain has built. The difference shows up primarily in the silent recovery rate before any emails or texts are sent.

Where Rekko Pulls Ahead

SMS Changes the Game

Retain is email-only for customer-facing recovery. Rekko sends both email and SMS. The numbers are straightforward:

• Email open rates: 20-25%
• SMS open rates: 90%+

When a customer doesn't open your recovery email, an SMS cuts through. For the subset of failed payments that need customer action (updating a card, confirming a charge), reaching the customer is everything. Multi-channel sequences recover more than email alone.

Independence and Predictability

Rekko is independent. It works with Stripe, charges a flat fee, and has no parent company pushing you toward a different platform. Your Rekko subscription costs the same this month, next month, and next year regardless of what happens in the broader market.

With Retain, you're tied to Paddle's strategic decisions. If Paddle decides Retain should only be available to Paddle billing customers in 2027, you'll need to migrate, either to Paddle or to a different recovery tool.

Sequence Control

Rekko gives you a visual sequence builder where you control every touchpoint: which channel, what message, what delay. You can A/B test different approaches and iterate based on your recovery data.

Retain's approach is more automated and less configurable. The ML handles timing, and you have limited control over the sequence logic. For teams who want to own their recovery strategy, this can feel like a black box.

Pricing Comparison

Rekko Pricing (Flat Monthly)

• Starter: $29/month (1,000 emails, 1 Stripe account)
• Essential: $49/month (5,000 emails, 3 Stripe accounts)
• Pro: $129/month (20,000 emails, unlimited accounts)
• SMS: Pay per use on all plans

ProfitWell Retain Pricing

• Historically: Pay-for-performance (percentage of recovered revenue)
• Currently: Varies, increasingly tied to Paddle platform adoption
• Typical cost: 5-15% of recovered revenue (or bundled with Paddle)
• ProfitWell Metrics (analytics) remains free

Cost Comparison

Performance-based pricing sounds appealing because you only pay when it works. But the absolute cost grows linearly with your success. Flat pricing means your recovery ROI improves as you grow.

Who Should Choose Rekko

Rekko is the better fit if:

• You're on Stripe and want to stay on Stripe
• You want email + SMS recovery sequences
• Predictable, flat pricing matters to you
• You want full control over your recovery messaging and timing
• Platform independence is important to your stack decisions
• You want to be live quickly without complex onboarding

Typical Rekko customer: SaaS company on Stripe that wants focused, multi-channel payment recovery without ecosystem commitments.

Who Should Choose ProfitWell Retain

Retain makes sense if:

• You're already on Paddle or planning to move to Paddle
• You value ML-optimized retry timing above all else
• You want the ProfitWell Metrics analytics dashboard alongside recovery
• You prefer a pay-for-performance model and your volumes are low
• You don't need SMS for recovery
• You're comfortable with the Paddle ecosystem direction

Typical Retain customer: SaaS company already in or moving to the Paddle ecosystem, valuing integrated analytics and automated recovery without manual sequence configuration.

What About Using Both?

If you like Retain's smart retries but want SMS outreach, you could theoretically use both. Retain handles silent retries in the background, and Rekko handles customer-facing email and SMS sequences. However, this introduces complexity and potential conflicts in recovery attribution. For most teams, choosing one tool is simpler and more effective.

The Bottom Line

Choose Rekko if you want an independent, multi-channel recovery tool with flat pricing and full control over your sequences. The combination of email + SMS on a predictable cost basis is hard to beat for Stripe-based SaaS companies.

Choose ProfitWell Retain if you're already in the Paddle ecosystem or planning to adopt it. Retain's ML retries are strong, and the integration with ProfitWell Metrics provides useful context. Just go in with eyes open about the platform direction.

The broader question is whether you want your recovery tool tied to a specific billing platform's roadmap, or whether you want an independent tool that focuses entirely on getting your money back. For most Stripe-based SaaS companies, independence and multi-channel reach provide more value.
