Brevo.com (formerly known as Sendinblue, rebranded in 2023) is a leading global all-in-one customer relationship and marketing platform. Headquartered in Paris, France, Brevo serves over 500,000 businesses worldwide. 

Brevo is the most intuitive all-in-one customer engagement platform: email and SMS marketing, automation, CRM, live chat, and transactional email. Try it free.

1. The Game-Changing Difference: Pay-per-Send Pricing

• Unlimited Contacts: On every single plan (including the Free tier), you can upload unlimited contacts for free.
• The Math: If you have a large list of 50,000 contacts but only email them once a month, Brevo is incredibly cheap. Conversely, if you have a tiny list of 1,000 contacts but email them daily, Brevo’s volume pricing can add up quickly.

2. Core Features & Capabilities

• World-Class Transactional Emails (SMTP): Brevo is globally renowned for its transactional email engine. It uses separate high-speed servers to deliver critical automated operational emails—such as account creation confirmations, shipping updates, and password resets—instantly to the inbox, completely bypassing the spam or promotions tab
• Multi-Channel Communication: Beyond email, Brevo acts as a multi-channel command center. From a single dashboard, you can natively build and deploy SMS marketing campaigns, WhatsApp campaigns, on-site Live Chat widgets, and manage a shared customer service inbox.
• Robust Marketing Automation: Even on budget tiers, Brevo provides a highly flexible visual workflow editor. You can set up automated customer journeys, such as sending a multi-day welcome sequence, tracking website behavior, or firing off abandoned cart triggers for e-commerce sites.
• Built-in Sales CRM & Pipelines: Brevo provides a free Sales CRM tool. It enables small sales teams to track deals, build sales pipelines, schedule meetings, and log client calls directly alongside their email data.
• Aura AI Engine: Its native AI suite features a smart subject line generator, automated text content optimizers, and a Send-at-Best-Time feature (Standard tier and above) that analyzes each contact's individual historical behavior to deliver emails exactly when they are most likely to open them.

3. Free Tier Breakdown

Brevo offers a Free Forever Plan that is highly usable for low-volume senders, freelancers, and businesses setting up their infrastructure:

• Contact Limit: Unlimited contacts.
• Daily Send Limit: Up to 300 emails per day (roughly 9,000 emails/month).
• What is Included: Transactional email tracking, basic marketing automation (capped at 2,000 contacts), SMS/WhatsApp marketing capabilities (pay-per-message), and the core Sales CRM.
• Major Restrictions: Free emails carry the "Powered by Brevo" logo, and advanced multi-user seats, A/B testing, and landing page editors are locked.

4. Limitations to Keep in Mind

• The Daily Free Cap Can Be Disruptive: The 300-emails-per-day limit on the free plan resets daily. If you have 400 contacts and try to send a single monthly newsletter, 100 of them will be paused until the next day unless you upgrade to a paid plan
• Paid Add-ons for Branding Removal: On the entry-level Starter plan ($9/mo), removing the Brevo logo from your email footer requires paying a separate, optional add-on fee. To get branding removal included natively, you must step up to the Standard plan ($18/mo).
• Interface Complexity: Because Brevo packages a full CRM, WhatsApp blaster, chatbot, and newsletter tool into one product, the user interface can occasionally feel overwhelming or cluttered compared to single-purpose alternatives like Kit (ConvertKit) or MailerLite.
