Drip

  • A Shopify retailer wants abandoned cart, winback and post-purchase automation without the tier-by-tier feature gating that makes Mailchimp and ActiveCampaign quotes unpredictable.not Inventory Lab

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Drip

  • Drip SMS is closed to new accounts and was US-only when it was open, so the multichannel positioning that competitors offer is not actually available to a new customer.
  • Pricing scales on total contacts regardless of engagement, so an unpruned list of lapsed subscribers costs the same as an active one and list hygiene becomes a direct budget item.
  • Analytics and revenue attribution are thinner than Klaviyo, with no predictive lifetime value or churn scoring, so a data-led ecommerce team hits the ceiling on measurement before it hits it on sending.
  • The integration catalogue is far smaller than Klaviyo or Mailchimp, and outside the main ecommerce platforms and Zapier you will often be writing against the API yourself.
  • It sits inside Leadpages rather than being an independent company, and as the smaller of the two products its roadmap is subject to a parent whose primary business is landing pages rather than ecommerce email.

Inventory Lab

  • InventoryLab is no longer sold standalone and is now bundled into Three Colts' Seller 365 plans starting at $69 per month for a single user, rising to $199 per month for the Pro tier
  • Multichannel listing requires the separate UniCon add-on, priced from $49 to $449 per month depending on tier
