Brevo's rapid expansion signals strong market momentum, particularly among SMBs seeking affordable, feature-rich alternatives to established platforms. This growth outpaces several legacy competitors.
The email marketing software category shows sustained, healthy growth at a 9.06% compound annual rate. This expansion reflects increased investment in platform capabilities like AI, automation, and deliverability.

AI capabilities are reshaping how marketers evaluate email software. These statistics show the percentage of users adopting AI features, expected growth in AI-driven operations, and measurable revenue impact from automation.
This represents a dramatic increase from 51% in Q1 2024, showing AI has become the standard approach rather than a competitive edge. Enterprise adoption reaches 94% while mid-market sits at 91%, indicating near-universal integration across organization sizes.
AI adoption in email marketing has reached critical mass, with over half now actively leveraging AI for personalization, subject line optimization, and send-time optimization. This adoption rate accelerates revenue performance when paired with proper workflow integration.
AI-powered personalization drives measurable business impact, with revenue increases of 41% and click-through rate improvements of 13.44% compared to non-personalized campaigns. This establishes AI as a revenue-generating rather than purely efficiency-focused tool.
Organizations are seeing faster ROI on AI investments, with content-heavy teams achieving payback in under three months. This accelerating ROI timeline reflects both tool maturity and increased organizational capability in deploying AI effectively.
Email marketing design has been dramatically transformed by AI, with image generation becoming one of the fastest-growing AI applications. This signals a shift from text-based AI assistance to multi-modal content creation capabilities.
Agentic AI represents the frontier of automation, where systems make autonomous decisions and execute complex workflows without human intervention. This adoption trajectory shows AI is moving beyond content generation into strategic decision-making and workflow execution.

Cost efficiency is critical when choosing email marketing platforms. These statistics cover pricing models, free plan usage, scaling costs, and ROI benchmarks that inform purchasing decisions.
Email delivers consistent high returns across industries. This benchmark is widely cited by multiple industry sources as the standard ROI metric, making it essential for evaluating whether email platform investments will pay off.
High-performing email programs using advanced automation and segmentation strategies achieve nearly 2x the industry benchmark, demonstrating that platform choice and strategy directly impact returns. This gap shows why paid platforms with robust automation justify their costs.
Litmus 2025 State of Email Survey data shows that over one-third of marketers achieve returns within this solid mid-range band, indicating that ROI performance varies significantly based on email strategy maturity and platform capabilities.
HubSpot's pricing for comparable contact lists is significantly higher than budget alternatives like Mailchimp. New customers considering enterprise email platforms should factor in upfront implementation costs that can reach thousands of dollars before sending the first campaign.
Mid-market email marketing software is substantially cheaper than enterprise platforms. For 10,000 contacts, costs reach just 100 dollars per month, offering cost-efficient scaling compared to platforms that charge per-user seat or tier-based pricing.
Significant pricing changes occurred mid-2025 when Validity acquired Litmus. The dramatic 151% increase eliminated affordable entry-level plans, forcing small teams to either absorb higher costs or switch platforms, highlighting how consolidation impacts email tool affordability.

Successful platforms meet strict deliverability and mobile standards. These statistics demonstrate how top tools perform on authentication requirements, mobile rendering, and inbox placement that users depend on.
DMARC pass rates improved significantly year-over-year, demonstrating growing adoption of mandatory authentication standards from Google and Yahoo. This metric directly affects inbox placement and sender reputation across major mailbox providers.
SPF adoption showed the biggest single-quarter improvement of any authentication protocol, reflecting enforcement pressure from Gmail and Microsoft. SPF remains essential for proving authorized sending servers.
Legitimate marketing emails face declining inbox placement, with 6.7% landing in spam and 9.8% missing entirely. This decline reflects stricter mailbox provider filters prioritizing engagement signals over volume.
While two-thirds of senders have implemented dual authentication, significant uncertainty persists around proper configuration. Gmail and Yahoo require both protocols for bulk senders (5,000+ daily emails) to avoid rejection.
DMARC adoption among high-profile domains nearly doubled in two years due to ISP mandates. However, only enforcement policies (quarantine or reject) provide real protection against spoofing and phishing attacks.
Mobile dominates email consumption patterns, yet responsive design remains absent in many campaigns. Emails that break or render poorly on mobile trigger higher spam complaint rates, damaging sender reputation.

Platform ratings and user growth signal market success. These statistics capture satisfaction scores, migration patterns, and market expansion data that define which platforms are gaining momentum in 2026.
Across email marketing platforms, user satisfaction consistently hovers near 4.5 out of 5 stars with a Net Promoter-like recommendation likelihood of 8.98, indicating strong overall buyer satisfaction with top-rated tools and their ease of use, support, and feature fit.
Mailchimp's NPS of 49 positions it at the top of email marketing platforms for customer loyalty and likelihood to recommend, outperforming SendGrid, LiveIntent, and GetResponse in willingness to refer the product to others.
Growing investment in email marketing software reflects increasing recognition of channel importance, with over half of sales and marketing professionals planning to increase budgets for email and SMS campaigns this year.
Cloud-based email marketing solutions dominate the market, driven by subscription pricing, elastic capacity, and continuous feature releases, with major players like HubSpot, Salesforce Marketing Cloud, and Klaviyo leading adoption among SMEs and enterprises.
Small and medium enterprises drive email marketing adoption, leveraging no-code tools and automation to offset rising social ad costs, with Klaviyo reporting that 80% of new customers in 2025 were SMEs shifting budget from social platforms to owned email channels.
Email marketing and sales software experiences elevated churn compared to other SaaS categories due to intense competition, feature commoditization, and purchase decisions made by individual contributors rather than executives, making platform satisfaction critical to retention.
