What the invoice doesn't show

Brevo

Brevo's free plan sends only 300 emails per day with Brevo branding on every email. The Starter plan ($9/mo for 5,000 emails) still includes Brevo branding — removing it costs an additional $9/month. You pay twice to look professional.

SMS and WhatsApp credits are purchased separately from email plans. SMS costs $0.014-0.06 per message depending on country. A campaign to 10,000 US contacts costs $140 in SMS credits alone — not included in any email plan.

The Business plan ($18/mo) is required for marketing automation, A/B testing, send-time optimization, and advanced stats. As of October 2025, landing page builder was also moved to Business — a feature previously available at the Starter tier now requires upgrading.

Brevo's CRM is functional but basic. Users report that deal pipeline management, contact scoring, and reporting lack the depth of dedicated CRMs, creating pressure to add a separate CRM tool and manage data across systems.

Constant Contact

Constant Contact's pricing scales aggressively with contact count. The $12/mo Lite price is for 500 contacts. At 10,000 contacts, Lite jumps to $120/mo, Standard to $160/mo, and Premium to $300/mo. A 50,000-contact list costs $430/mo on Premium.

Lite plan limits email sends to 10x your contact count per month and blocks all automation. Even basic welcome sequences require Standard ($35/mo for 500 contacts). This means the '$12/mo' plan can't do what most businesses need email marketing for.

Constant Contact's email editor and templates are widely described as dated. Users report limited design flexibility, clunky drag-and-drop building, and templates that look like they haven't been updated since 2015.

Contract cancellation requires calling customer support. Users report being charged for months after requesting cancellation via email, with refunds requiring escalation to management.

Which one fits your team?

Both Brevo and Constant Contactcost more than their published pricing suggests. The right choice depends on your team size and how you weigh each tool's trade-offs.

Brevo starts at $18/seat/mo , but watch for Brevo's free plan sends only 300 emails per day with Brevo branding on every email. The Starter plan ($9/mo for 5,000 emails) still includes Brevo branding — removing it costs an additional $9/month. You pay twice to look professional.

Constant Contact starts at $12/seat/mo , but watch for Constant Contact's pricing scales aggressively with contact count. The $12/mo Lite price is for 500 contacts. At 10,000 contacts, Lite jumps to $120/mo, Standard to $160/mo, and Premium to $300/mo. A 50,000-contact list costs $430/mo on Premium.

An AI-native alternative may replace the workflow at a fraction of the TCO.
