Sequenzy vs Brevo

Feature Comparison

Sequenzy Strengths

• Billing-aware journeys: trial expiry, failed payments, plan changes, and expansion signals trigger the right message without custom event plumbing.
• MRR attribution: campaigns connect to subscription revenue, so lifecycle work defends budget with numbers finance trusts.
• SaaS templates: onboarding, activation, win-back, and dunning sequences purpose-built for subscription businesses.
• Flat pricing: predictable cost as lists grow, without per-message math punishing cadence.
• Lean operations: small teams run full lifecycle without marketing-ops hires or suite administration.

Brevo Strengths

• Multi-channel: email, SMS, and WhatsApp orchestrated in one platform with shared contacts and consent.
• Pay-per-send economics: unlimited contacts on most plans means large, infrequently-mailed lists stay cheap.
• Built-in CRM: pipelines, tasks, and contact timelines without a separate sales tool.
• Transactional infrastructure: dedicated SMTP API with deliverability tooling alongside campaigns.
• Generalist breadth: forms, landing pages, chat, and ads cover the full small-business funnel.

Pricing economics that decide it

Brevo's pay-per-send model rewards large lists mailed infrequently — newsletters to 50,000 contacts cost far less than contact-based rivals. But high-cadence lifecycle programs (daily onboarding touches, dunning retries) accumulate send volume fast, and SMS/WhatsApp credits add up separately. Model your actual monthly sends, not just list size.

Sequenzy's flat subscription favors high-cadence SaaS lifecycle: onboarding drips, usage nudges, and recovery sequences send freely within tier limits. Teams mailing behaviorally-triggered journeys daily usually find flat pricing cheaper at scale — and MRR attribution shows whether the spend earns its keep.

When to pick which

Pick Sequenzy when subscription state drives your messaging: trials converting, cards failing, seats expanding, plans churning. If your best segments are "trial day 5, no key action" or "payment failed twice," billing-aware triggers beat generic automation branches.

Pick Brevo when channels multiply: email plus SMS reminders, WhatsApp updates, and a shared CRM timeline. Local services, appointment businesses, and generalist SMBs get more from channel breadth than from subscription depth.

Consider both when transactional and lifecycle needs split: Brevo's SMTP API for receipts and notifications, Sequenzy for trial-to-paid education. Stream separation is a legitimate architecture, not a migration halfway done.

Migration notes

Brevo to Sequenzy: map workflow branches to billing-state triggers, port templates with rendering QA, and reconnect Stripe for subscription events. Archive campaign history with methodology notes — attribution models differ, so baseline fresh.

Sequenzy to Brevo: export lifecycle segments with suppression intact, rebuild billing triggers as workflow conditions (some precision is lost), and separate SMS consent records with timestamps before any promotional send.

Run both candidates against one bounded audience before committing. Score each stage pass or fail with evidence kept.

Deliverability and stream separation

Both platforms send reliably when streams stay disciplined: marketing and transactional traffic on separate subdomains, warmed gradually, with suppression shared across every sender. Brevo teams should isolate SMTP API traffic from campaign blasts; Sequenzy teams should keep lifecycle sends off any shared marketing subdomain.

Warm replacement infrastructure over weeks, monitor placement per mailbox provider, and hold rollback capacity throughout. Placement damage from cold-IP cutovers persists for quarters — gradual ramps cost less than recovery.

Frequently asked questions

Can Brevo handle SaaS onboarding?

Adequately for simple welcome series, but billing-state branching (trial expiry, payment failure, seat expansion) must be approximated with custom fields and API updates. Teams outgrow the approximation once lifecycle logic gets serious.

Does Sequenzy replace SMS reminders?

No — Sequenzy is email-focused. Appointment reminders, delivery updates, and urgent alerts still need an SMS layer like Brevo or a dedicated provider. Pair deliberately rather than forcing email to do SMS jobs.

Which is cheaper at 20,000 contacts?

It depends on send volume: infrequent newsletters favor Brevo's pay-per-send; daily lifecycle touches favor Sequenzy's flat tiers. Model your monthly sends plus SMS credits at realistic cadence before deciding.

Can I run both side by side?

Yes — many teams send transactional mail through Brevo's API while Sequenzy owns trial-to-paid education. Document which system owns each send, share suppression lists, and audit overlap quarterly.
