CLVTools vs Pushwoosh

CLVTools is a free, GPL-3-licensed R package for probabilistic customer attrition modeling when purchases are not governed by contracts. It implements Pareto/NBD, BG/NBD, Gamma/Gompertz/NBD, and Gamma/Gamma models. Using transaction histories with customer IDs and purchase dates, plus prices in its example data, it predicts individual customer behavior such as expected future transactions and the probability that a customer remains active. Forecast horizons can be configured, supporting predictive customer lifetime value work, cohort analysis, and customer segmentation. Time-invariant covariates work across the models, while some models accept time-varying covariates. Extensions include correlated purchase and attrition processes, L2 regularization, and equality constraints for contextual-factor parameters. Stable installation is available from CRAN; a development version uses GitHub and devtools. Linux, macOS, and Windows are supported, though compiling from source requires the external GNU GSL C++ library. Documentation includes a walkthrough, reference manual, and vignettes.

Pushwoosh is a customer messaging and engagement platform for mobile and web audiences. It supports mobile push and in-app messages, web push, email, SMS, WhatsApp, Kakao Talk, and Telegram, with tools for segmentation, personalization, analytics, A/B testing, Journey Builder workflows, and autonomous AI optimization.

The free plan covers projects with up to 1,000 monthly active users and includes unlimited push notifications, unlimited in-app impressions, and 20,000 email sends monthly; extra email sends cost $1.50 per 1,000. Listed paid plans are Email only at $5.00 per month, Push only at $7.00 per month, and Omnichannel at $13.00 per month. Plans bill by monthly active users or monthly unique email recipients. Pushwoosh says setup through SDK integration, user import, and initial subscriber collection takes 2 to 10 days. It states a 99.9% uptime commitment and lists GDPR and ePrivacy compliance, ISO 27001:2022 certification, SOC 2 Type 2 auditing, and HIPAA compliance.
