Why we built GetFluxly instead of using Brevo for SaaS lifecycle email.
Brevo (formerly Sendinblue) is one of the best value all-in-one marketing platforms you can buy. We built GetFluxly anyway, because SaaS lifecycle email is a different job: it fires on what users do inside your product, not on how many emails you send to a list.
The search for a Brevo alternative for SaaS usually starts the same way. You have a product, you have real users doing real things inside it, and you want to send the right email at the right moment based on their behavior. You look at Brevo, which everyone recommends for email marketing, and you realize it is priced on how many emails you send, not on what your users did to trigger them.
That is not a criticism of Brevo. It is the right model for a newsletter, a promotional blast, or a multichannel marketing campaign for a business with a large list. For SaaS lifecycle email, the model is just different. You are not sending to a list on a schedule. You are sending to a specific user because they did something specific in your product minutes ago.
That is the gap GetFluxly fills. Read our full comparison of GetFluxly vs Customer.io if you are evaluating tools more broadly, or see the SaaS lifecycle email automation guide for the full picture of what a good lifecycle stack looks like.
Four things Brevo does better.
Brevo is a mature, well-funded platform with real strengths. These are the cases where it is the right choice.
All-in-one multichannel platform.
Email, SMS, WhatsApp, push notifications, live chat, and a CRM all live under one roof. If your business touches customers across several channels and you want one tool to manage all of them, Brevo is genuinely hard to beat for the price.
Priced on email volume, not contacts.
Brevo bills on the number of emails you send, not the size of your list. If you have a large contact base but send infrequently, that model can be significantly cheaper than tools that charge per subscriber. For newsletters and broadcast campaigns, this is a real advantage.
Strong SMB and ecommerce integrations.
Shopify, WooCommerce, WordPress, Stripe, and 150-plus direct integrations make Brevo a natural fit for online stores and small businesses that want marketing tied to their sales platform without custom engineering.
Generous free tier.
Brevo offers a permanent free plan that allows up to 300 emails per day with unlimited contacts. For very early-stage projects that just need occasional outreach, that is a workable starting point before any paid commitment.
Three things GetFluxly does better for SaaS.
Triggers on what users actually do in your product.
GetFluxly automations start from real product events: trial started, feature used, payment failed, limit reached. You send the event and the flow fires. Brevo event-based triggers exist on the Standard plan and above, but they are designed around website behavior and contact attribute changes, not the custom events emitted by your SaaS backend.
First party product analytics in the same tool.
GetFluxly includes a JavaScript SDK that auto-captures pageviews, clicks, and forms, and an HTTP Events API for server-side events. Both write to the same customer profile. There is no separate analytics tool to wire up before you can build a segment or trigger a flow.
Anonymous to identified profile stitching, built in.
When an anonymous visitor on your marketing site eventually signs up and becomes a known user, GetFluxly unifies those sessions automatically. The full pre-signup journey is already on the profile when the first email fires. Brevo does not have a comparable anonymous identity resolution layer for SaaS products.
Pricing, side by side.
Brevo and GetFluxly use completely different billing models. Brevo charges by how many emails you send per month. GetFluxly charges by pooled profiles plus an events guardrail. Which is cheaper depends entirely on your usage pattern. As of June 2026:
| GetFluxly | Brevo | |
|---|---|---|
| Free plan | Yes (Hacker, $0, no card) | Yes, 300 emails/day, unlimited contacts |
| Entry paid price | $39/mo (Starter) | Starter, from approx. $9/mo for 5,000 emails/mo |
| Billing model | Pooled profiles + events guardrail | Email volume per month |
| Marketing automation | All tiers | Standard plan and above |
| Product event triggers | Yes, native (all tiers) | Via event tracking API, Standard and above |
| Built-in product analytics | Yes (JS SDK + HTTP Events API) | No |
| SMS / WhatsApp | No (email only) | Yes |
| Free trial (paid plan) | 14 days Growth level, no card | Free tier available; no paid trial advertised |
Brevo sends by volume. GetFluxly sends by behavior.
The clearest way to state the difference: Brevo is optimized for the question "how many people should I email today?" GetFluxly is optimized for the question "what did this specific user just do, and what should I send them because of it?"
Both are legitimate questions. Newsletters, product announcements, promotional campaigns, and SMS blasts all live on the Brevo side. Trial onboarding, feature adoption, churn risk detection, and payment recovery all live on the GetFluxly side. Read the guide to product event tracking for email to understand how the event layer works in practice.
GetFluxly sends email through Resend, Mailgun, AWS SES, or any SMTP relay you already operate. Native sending is coming in a future release called GetFluxly Mail. Brevo handles sending infrastructure natively and that is part of what you pay for. If you want to bring your own ESP and keep those costs separate, GetFluxly is the right shape. See our integrations page for the full list of supported providers.
When Brevo is the right tool.
Be honest with yourself about what you actually need. Brevo is the better choice if any of the following describes your situation:
- You run an SMB, ecommerce store, or local business and want email plus SMS plus CRM in one tool without engineering work.
- Your email program is primarily newsletters and promotional broadcasts to a large list, and you want volume-based pricing.
- You need WhatsApp campaigns, live chat, or phone support in the same platform.
- You want a mature, well-supported tool with 600,000 customers and extensive documentation in multiple languages.
None of those are wrong reasons to choose Brevo. We would rather you make the right tool choice than pick GetFluxly and discover it is the wrong fit.
When GetFluxly is the right tool.
GetFluxly is the better fit if you are building a SaaS product and your email program is supposed to react to what users do inside it. Specifically:
- You want lifecycle emails (onboarding, activation, churn risk, win-back) that fire based on real in-app events, not a time-based drip on a list.
- You want product analytics, behavioral segmentation, and email automation in one tool so you are not managing two separate systems that disagree about what a user is.
- You want anonymous to identified profile stitching without a separate CDP or identity layer.
- You are pre-revenue or early stage and need a free starting point (Hacker tier, $0) with no feature gating as you scale to paid.

Brevo vs GetFluxly, answered.
Is Brevo good for SaaS product emails like trial onboarding and activation?
Brevo is a capable marketing platform but it is designed around contact lists and email volume, not product event triggers. Event-based triggers require the Standard plan and are built for website behavior, not custom server-side events like trial_started or feature_used that SaaS lifecycle email depends on. For dedicated SaaS lifecycle email triggered by in-app behavior, a tool built specifically for that job fits better.
Does Brevo have a free plan?
Yes. As of June 2026, Brevo offers a permanent free plan that allows up to 300 emails per day with unlimited contacts. Marketing automation and event tracking are not included on the free plan; those features require the Standard plan.
How does GetFluxly pricing compare to Brevo?
GetFluxly has a Hacker tier at $0 with no credit card required and paid plans starting at $39 per month, billed on pooled profiles plus an events guardrail. All paid tiers include every feature, with no gating by plan. Brevo is priced on email volume, so cost scales with how many emails you send per month rather than how many users are in your account.
Can I use Brevo for behavior-triggered lifecycle emails?
Technically yes, on the Standard plan and above. Brevo added web and event tracking so you can trigger automations from custom events. In practice, wiring your SaaS backend to fire custom Brevo events requires API work, and the automation builder is optimized for contact attributes and list conditions rather than real-time product event streams.
What is the difference between Brevo (formerly Sendinblue) and GetFluxly?
Brevo (formerly Sendinblue) is a multichannel marketing suite: email, SMS, WhatsApp, CRM, and chat for businesses that want everything in one tool, priced on email volume. GetFluxly is focused on SaaS lifecycle email triggered by product behavior, with built-in product analytics, anonymous to identified profile stitching, and behavioral segmentation. Different tools for different jobs.
Does GetFluxly replace Brevo for SMS or WhatsApp marketing?
No. GetFluxly is an email-first tool. If your business requires SMS, WhatsApp, or multichannel campaign management alongside email, Brevo is the stronger choice for that use case. GetFluxly focuses on getting the email layer right for SaaS teams: sending through Resend, Mailgun, AWS SES, or any SMTP relay, triggered by real product events.
Brevo is the tool we would recommend if you need multichannel marketing for a business with a large list. GetFluxly is the tool we built for the SaaS founder who needs the right email to fire the moment a user does something meaningful inside the product. Those are different jobs, and one tool does not replace the other.
