The short version: Mailchimp prices on contact-list size; Nudge prices on actual sends. If your list is bigger than your monthly send volume, Mailchimp's contact-based model means paying for emails you never send. Nudge also bundles SMS, WhatsApp, voice, and push notifications in the same plan — Mailchimp doesn't.
| Dimension | Nudge | Mailchimp |
|---|---|---|
| Pricing model | Token-based (per send) | Contact-based (per subscriber) |
| SMS in same platform | ✓ Yes | ~ Add-on, separate pricing |
| WhatsApp Business | ✓ Yes | ✗ Not offered |
| Voice / IVR | ✓ Yes | ✗ Not offered |
| Transactional email (OTP, receipts) | ✓ Same plan | ~ Mailchimp Transactional (separate) |
| Marketing automation | ✓ | ✓ Larger ecosystem |
| Visual drag-and-drop builder | ✓ | ✓ Industry-leading |
| Industry billing templates | ✓ Utilities, healthcare | ~ Generic / e-commerce |
| TCPA / FDCPA tooling | ✓ Built-in | ✗ Not focused on this |
| HIPAA | ✓ Compliant | ✗ Not HIPAA-compliant |
| Built-in payment processing | ✓ tilliPay | ✗ |
| Pricing | Contact for pricing | Tiered by contact-list size |
If you're a small e-commerce store doing newsletter campaigns, Mailchimp's marketing tooling and templates are probably worth it. If you're sending billing notifications, payment reminders, or transactional email at scale — especially in regulated industries — Nudge's token-based pricing is typically more efficient, plus you get SMS and WhatsApp in the same platform and HIPAA / TCPA tooling Mailchimp doesn't offer.
Mailchimp's contact-based pricing charges you based on the size of your subscriber list, regardless of how many of them you actually email in a given month. A list of 50,000 subscribers pays a 50,000-contact tier even if only 5,000 are emailed that month.
Nudge's token-based pricing decouples list size from cost. You pay for sends, not for stored contacts. This is a meaningfully better fit for billing-style use cases:
For these patterns, the contact-based model effectively penalizes you for retaining customer data — a payment for inventory rather than activity.
Nudge pricing is finalized per organization based on volume and channel mix. To estimate against your current Mailchimp spend, contact sales@tilli.pro or use the ROI calculator.

The pricing models differ structurally. Mailchimp uses contact-based pricing — you pay based on the size of your subscriber list whether or not you email them in a given month. Nudge uses token-based pricing — you pay only for actual sends. For organizations with large subscriber lists relative to monthly send volume (utilities, healthcare, insurance), token-based pricing is typically more efficient. Nudge pricing is finalized per organization based on volume and channel mix — contact sales or use the ROI calculator for a tailored quote.
Contact-based pricing (Mailchimp, Klaviyo, Constant Contact) charges you for every subscriber on your list — even if you don't email them in a given month. Token-based pricing (Nudge) charges you for actual sends. If you have a large subscriber list but only email a subset of them per month, contact-based providers charge for the full list while token-based providers only charge for what you send.
Yes for most use cases. Nudge supports campaign creation, drip sequences, segmentation, A/B testing, dynamic content, and automation triggers — the core Mailchimp toolkit. Where Mailchimp specializes more is in e-commerce integrations and visual campaign builders for non-technical marketers; Nudge specializes more in transactional notifications and multi-channel (email + SMS + WhatsApp) automation.
Yes. Nudge handles transactional email (password resets, receipts, OTP, billing notifications) in the same plan as marketing email. Mailchimp Transactional (formerly Mandrill) is a separate product priced separately from the marketing tiers.
Yes — all in the same plan. Mailchimp offers SMS as an add-on but does not offer WhatsApp Business or voice. For multi-channel campaigns spanning email + SMS + WhatsApp, Nudge handles all three natively, while a Mailchimp stack would require separate Twilio Conversations and SMS subscriptions.
Nudge integrates with enterprise systems: SAP (S/4HANA, ECC), Oracle (E-Business Suite, Cloud), Salesforce, Microsoft Dynamics, and Oracle Utilities CC&B. Mailchimp's integration ecosystem is broader on the e-commerce side (Shopify, WooCommerce, Squarespace) but thinner on enterprise billing and CRM systems.
Yes — and arguably a stronger fit than Mailchimp for those verticals. Nudge ships with industry-specific templates for billing notifications, payment reminders, and outage alerts, plus built-in TCPA, FDCPA, and HIPAA tooling. Mailchimp is engineered primarily for retail and e-commerce marketing, not regulated billing communications.
Token-based pricing decouples list size from cost — plus you get SMS, WhatsApp, and voice in one platform.
