Overview
Keap and Selzy represent very different approaches to business software. Keap is a full CRM and business automation platform that includes email marketing as one of many features. Selzy is a focused email marketing tool built for SMBs who want effective campaigns without CRM complexity. The 6x price difference tells the story. See our Keap comparison page for more context.
Do You Need a CRM or Email Marketing?
This is the question that decides everything. If you're a service business managing client relationships, sending invoices, processing payments, and scheduling appointments - and you want all of that alongside email marketing - Keap consolidates those functions. If you have a separate CRM (or don't need one) and just want to send email campaigns and set up automations, Selzy handles that well at a fraction of the cost.
The Cost of Complexity
Keap's all-in-one approach creates complexity. New users regularly report needing weeks to feel comfortable with the platform. Selzy, by contrast, lets you send your first campaign within hours. For small marketing teams without dedicated ops staff, Keap's learning curve can be a real productivity drain. Consider whether the CRM features justify the added complexity for your team size.
Automation Comparison
Keap shines when automation spans multiple business functions - for example, sending an invoice when a deal closes, then triggering a follow-up email sequence based on payment status. Selzy's automation is email-focused: drip sequences, behavioral triggers, and scheduled campaigns. Both work well within their scope, but Keap's cross-system automation is genuinely more powerful. For SaaS-specific automation with payment triggers, Sequenzy offers a focused alternative.
The Honest Recommendation
For most small businesses, Selzy provides everything needed for effective email marketing at ~$50/month. The $250/month saved versus Keap adds up to $3,000/year. Only commit to Keap if you'll actively use CRM pipelines, invoicing, and payment processing daily. If you're a SaaS company, consider Sequenzy for Stripe-native email at $49/month.
Use-case matchups
| Situation | Best first look | Why |
|---|---|---|
| Service business needs CRM, invoices, payments, and follow-up | Keap | Keap is built around the client record and business workflow, not just campaigns. |
| SMB wants lower-cost newsletters and simple automations | Selzy | Selzy keeps the buying decision focused on email marketing instead of CRM operations. |
| SaaS team needs Stripe-triggered email | Sequenzy | Sequenzy is a better fit when billing events and product lifecycle messages matter more than CRM pipelines. |
| Team already has a CRM | Selzy | Paying Keap pricing only for email is hard to justify if CRM is already handled elsewhere. |
| Solopreneur wants one place for sales follow-up and payments | Keap | The higher cost makes more sense when the non-email modules replace separate tools. |
Best Fit by SMB Email and Client Operations
Best email marketing tool for cost-conscious SMBs
Choose Selzy when the team wants campaigns, simple automations, forms, and basic email marketing at a much lower monthly cost. It is the better fit when the CRM is already solved, when billing happens elsewhere, or when the team needs to launch campaigns quickly without onboarding a full service-business platform.
Best CRM and invoicing platform for solopreneurs
Choose Keap when one person or a small team needs lead capture, appointments, invoices, payments, and follow-up to run from a single customer record. Keap's cost makes more sense when the alternative is juggling a CRM, scheduler, invoicing app, and manual follow-up process.
Best platform for SaaS billing-triggered email
Choose Sequenzy when the business is not choosing between CRM depth and low-cost SMB email. SaaS teams need trial, payment, upgrade, cancellation, and transactional messages to react to Stripe and product events, which is a narrower job than either Selzy or Keap is built around.
Pricing reality
Keap's $299/month signal only makes sense if the team will actively use CRM, invoicing, payments, scheduling, and automation together. If email campaigns are the only requirement, Keap is expensive for the job.
Selzy's ~$50/month positioning is more practical for email-only teams, but confirm the subscriber tier, included send volume, SMS availability in your region, and any deliverability or support limits before switching.
Sequenzy sits close to Selzy's price in this comparison, but it is narrower: SaaS-focused lifecycle, Stripe, transactional email, and marketing email without Keap's CRM or Selzy's broader SMB email toolkit.
Review signals
| Platform | What reviews in this page suggest | What to validate |
|---|---|---|
| Keap | Buyers value the all-in-one CRM, invoicing, and follow-up workflow, while calling out price and learning curve. | Confirm your team will use the CRM and payment modules often enough to justify the complexity. |
| Selzy | Buyers value a clean interface, reasonable automation, and affordable email marketing. | Confirm automation depth, integrations, and regional SMS support before replacing a broader platform. |
Migration checklist
| Workstream | Moving toward Keap | Moving toward Selzy | Moving toward Sequenzy |
|---|---|---|---|
| Contacts | Map CRM fields, lead stages, tags, consent, and duplicate rules. | Export subscribers, tags, lists, suppression status, and engagement fields. | Map subscribers, lifecycle attributes, tags, and billing identifiers. |
| Business records | Decide which invoices, payments, appointments, and pipeline records need migration. | Keep CRM, invoice, and payment history in separate systems. | Keep CRM and invoicing outside Sequenzy unless Stripe events drive email. |
| Automations | Rebuild follow-up flows across deals, invoices, payments, and email. | Rebuild email sequences, welcome flows, reactivation, and campaign segments. | Rebuild Stripe, product, transactional, and newsletter flows. |
| Templates | Recreate email templates and forms; test personalization fields. | Recreate campaign templates, signup forms, and landing pages. | Recreate product and lifecycle email templates. |
| Reporting | Define CRM pipeline, invoice, payment, and email reporting needs. | Define campaign, automation, list growth, and engagement reporting. | Define lifecycle, transactional, and billing-event reporting. |
Decision checklist
- Are you buying CRM and business operations, or only email marketing?
- Will Keap replace enough tools to offset its monthly cost and learning curve?
- Does Selzy's automation depth cover the flows you actually run?
- Do you need Stripe-native SaaS lifecycle email more than CRM or landing pages?
- Which system will your team keep cleaner: CRM records, subscriber lists, or billing events?
