Two tools that both say "SaaS"
Most tools compared with PostHog Workflows are general email or engagement platforms. Encharge is different: it markets itself squarely to B2B SaaS. That makes this a closer comparison, and the answer depends more on who in your company owns lifecycle than on features.
- PostHog Workflows belongs to the product team. It lives inside PostHog, triggers from events and cohorts, and can send email or SMS, post to Slack, call webhooks, and update properties.
- Encharge belongs to the marketer. It has a visual flow builder, segments, lead scoring, Stripe and Chargebee integrations, and CRM syncs with HubSpot and Salesforce on its higher plan.
If your product manager builds the onboarding nudges, PostHog Workflows removes a tool. If a growth marketer runs trial conversion, Encharge gives them a workspace that fits.
A trial conversion flow in each tool
Take a common job: a 14-day trial where you want to nudge inactive users, push active users to upgrade, and follow up if they churn.
In PostHog Workflows, the trigger is a "trial started" event you already capture. You split on a cohort like "created at least one project," send different emails, and wait. The hard part is billing: "trial converted" or "trial expired" only exist if your app tracks them into PostHog. Once they do, you can also alert a Slack channel when a large account converts.
In Encharge, the trigger can come straight from Stripe or Chargebee, so trial and subscription changes are available without engineering. Product usage is the harder part. To branch on "created a project," you need that event in Encharge, which means API events or Segment on Premium, or a webhook or Zapier workaround on Growth.
So each tool is strong on one half of the flow and needs integration work on the other.
The Growth versus Premium question
Encharge's plan split matters more than the headline price for a PostHog user. From our Encharge pricing notes:
| Growth | Premium | |
|---|---|---|
| Monthly price at 2,000 subscribers | $99, or $79 billed annually | $159, or $129 billed annually |
| Monthly sends | 10x subscriber limit | 12x subscriber limit |
| Stripe, Chargebee, webhooks, Zapier | Included | Included |
| API events, Segment, event-based segmentation | Not listed | Included |
| Transactional emails | Not listed | Included |
| HubSpot, Salesforce, custom objects | Not listed | Included |
If your plan is to forward PostHog events into Encharge, you will most likely want Premium. That is worth knowing before you compare it with PostHog Workflows, which includes 10,000 messages per channel free each month and charges per message after that.
Where billing data should come from
Both tools can see billing data, but by different routes, and that decides a lot of your setup.
Encharge connects to Stripe and Chargebee on Growth. Subscription created, trial ending, payment failed, and plan changed become flow triggers without code. That is its clearest advantage for SaaS marketers.
PostHog offers a Stripe source for its data warehouse, which syncs Stripe tables such as customers, subscriptions, invoices, and charges so you can join revenue to product usage in analysis. That is excellent for questions like "which features do paying accounts use." For triggering a workflow the moment a card fails, most teams still send a billing event into PostHog from their backend or a Stripe webhook handler.
If billing triggers are central to your lifecycle program and you do not want to write that plumbing, Encharge has the shorter path.
Pricing reality at 2,000 trial users
Assume a B2B product with 2,000 active trials and customers, a six-email trial sequence for about 400 new trials a month, and a monthly update to everyone.
| Line | PostHog Workflows | Encharge Growth | Encharge Premium |
|---|---|---|---|
| Monthly sends | About 2,400 trial plus 2,000 update emails | Same | Same |
| Send cap | Not applicable | 20,000 | 24,000 |
| Listed price | Inside the free email allowance | $99 monthly or $79 annually | $159 monthly or $129 annually |
| Product events from PostHog | Native | Webhooks or Zapier | API events or Segment |
The comparison is not really about the send volume, which is small. It is about whether the Encharge features, Stripe triggers, lead scoring, CRM sync, and a marketer's workspace, are worth $79 to $159 a month to your team.
Where PostHog Workflows wins
- No second event pipeline. Product behavior is already in PostHog.
- Internal automation. Slack alerts, webhooks, and property updates from usage.
- Cost at low volume. Early products may pay nothing.
- Measurement. Workflows sit next to the funnels you use to judge them.
Where Encharge wins
- Billing triggers without code through Stripe and Chargebee.
- Lead scoring and CRM sync for sales-assisted trials.
- A marketer's workspace with flows, segments, and email reporting designed for them.
- Unlimited flows and team members on both plans.
Migrating from PostHog Workflows to Encharge
- Export identified users with email, plan, and the properties your flows need, and import them as Encharge subscribers. Watch the count, since it sets your plan price.
- Connect Stripe or Chargebee so billing state flows in directly.
- Choose how product events will arrive: API events or Segment on Premium, or webhooks from PostHog.
- Rebuild each PostHog cohort as an Encharge segment and each workflow as a flow.
- Authenticate your sending domain in Encharge and import unsubscribes.
- Leave Slack and webhook-only workflows in PostHog.
Going the other way, from Encharge to PostHog Workflows, you lose lead scoring, CRM syncs, and the Stripe integration, and you need billing events tracked in PostHog before flows can use them.
Use-case matchups
| Need | Better fit | Why |
|---|---|---|
| Nudge trials who have not created a project | PostHog Workflows | Usage cohort already exists |
| Flow triggered by a Stripe subscription change | Encharge | Native Stripe integration |
| Score trials for sales follow-up | Encharge | Lead scoring built in |
| Slack alert when a trial account hits a threshold | PostHog Workflows | Native Slack step |
| Sync lifecycle stage to Salesforce | Encharge Premium | Salesforce integration |
| Transactional and lifecycle email on one plan | Sequenzy | Both included |
Subscriber count math for product-led SaaS
Encharge's model rewards teams whose subscriber list is close to their paying customer base. The entry tiers are quoted at up to 2,000 subscribers, and each plan's send allowance is a multiple of that limit: 10x on Growth and 12x on Premium, so a Growth account at the 2,000 tier can send up to 20,000 emails a month. That is plenty for a B2B product with a few thousand qualified trials.
It is less comfortable for a product-led SaaS with tens of thousands of free signups. Every subscriber you import moves you up a tier, even if you only email them twice a year. The usual workaround is to import only trials, active users, and customers, and to leave long-dormant free accounts out. PostHog Workflows avoids the question entirely because it charges per message, not per person, but it also lacks the marketer tooling that makes Encharge worth paying for.
Decision checklist
- Who owns lifecycle? A marketer points to Encharge. A product team points to PostHog Workflows.
- Is billing the main trigger or usage? Billing favors Encharge's integrations. Usage favors PostHog.
- Will you forward PostHog events? Budget for Encharge Premium.
- How large is your subscriber base? Large free tiers make subscriber pricing costly.
- Do you need lead scoring or CRM sync? Encharge has them. PostHog Workflows does not.
Where Sequenzy fits
Encharge and Sequenzy both care about SaaS billing moments. The differences are pricing and scope. Encharge prices by subscribers and lists transactional email on Premium. Sequenzy prices by emails sent with unlimited contacts and includes transactional email alongside lifecycle sequences, with Stripe connected for trial, dunning, and upgrade email. The comparison plan at 10,000 contacts is $49/month for 60k emails (unlimited subscribers).
If you need lead scoring and Salesforce sync, Encharge covers that and Sequenzy does not. If you want focused SaaS email with PostHog as your analytics layer, Sequenzy is the simpler fit.
Picking one
Product team, analytics-first, internal alerts: PostHog Workflows. Marketer-owned SaaS lifecycle with billing triggers and CRM: Encharge. SaaS email with billing and transactional together on send-based pricing: Sequenzy.
