While Constant Contact remains a household name and beginner-friendly features, the platform's premium pricing and limited automation capabilities push B2B SaaS companies toward more sophisticated alternatives. While Constant Contact highlights strong deliverability in its marketing, independent tests suggest that real-world performance may be somewhat lower than advertised. From multichannel powerhouses like Brevo to enterprise-grade platforms like HubSpot, these seven alternatives deliver superior automation, better value, and stronger GTM alignment for scaling companies. This comprehensive analysis examines each platform's strengths, pricing models, and ideal use cases to help B2B SaaS marketing leaders make informed decisions beyond Constant Contact.

Key Takeaways

• Automation depth separates growth-ready platforms from basics: Constant Contact offers limited automation on lower tiers, while ActiveCampaign and Brevo deliver advanced multi-step workflows at comparable or lower price points—critical for B2B SaaS companies executing complex nurture sequences

• Contact-based pricing penalizes list growth: Constant Contact’s Standard plan starts around $30/month for 500+ contacts, while Brevo uses high contact limits with email-based pricing, enabling more predictable budgeting as your database scales

• Built-in CRM eliminates costly add-ons: Constant Contact’s CRM is a separate platform starting around $449/month, whereas Brevo and ActiveCampaign include native CRM at entry pricing—representing up to $5,388 in potential annual savings for B2B teams needing sales-marketing alignment

• Multichannel capabilities define modern email marketing: Brevo integrates Email, SMS, and WhatsApp in one platform from $9/month (higher tiers for full multichannel), while Constant Contact charges separate add-ons for SMS starting at $10/month

• Template modernization matters for brand perception: Independent reviews consistently note Constant Contact's templates as "dated" compared to alternatives, impacting conversion rates for product-led B2B SaaS companies

The email marketing landscape has transformed dramatically for B2B SaaS companies in 2026, with marketing automation and CRM integration becoming table stakes rather than premium features. While Constant Contact maintains its position as an accessible entry point with strong phone support, seven alternatives stand out for superior automation, value delivery, and GTM alignment.

1. Brevo — Multichannel Marketing at Entry-Level Pricing

Brevo (formerly Sendinblue) emerges as the most compelling Constant Contact alternative for B2B SaaS companies seeking multichannel capabilities without enterprise budgets.

For a 1,000-contact database, Brevo typically costs roughly $110–$220 annually, compared to Constant Contact’s approximately $600–$700—while Brevo includes built-in CRM features that Constant Contact offers through a separate CRM platform starting around $449/month (~$5,388 annually).

Frequently Asked Questions

What are the primary differences between Constant Contact and alternatives like Brevo and ActiveCampaign?

Constant Contact prioritizes simplicity and event management at premium pricing, while alternatives offer superior automation and value. Brevo includes multichannel marketing (Email + SMS + WhatsApp) and built-in CRM at $9/month versus Constant Contact's $12/month for basic email only. ActiveCampaign provides 1,000+ integrations and advanced automation that Constant Contact reserves for premium tiers. The CRM gap is particularly significant—Constant Contact charges $449/month for CRM while both Brevo and ActiveCampaign include it at entry pricing.

Which alternative offers the best marketing automation for B2B SaaS companies?

ActiveCampaign leads for complex B2B nurture sequences with visual workflow builders, conditional logic, lead scoring, and predictive sending. HubSpot provides the deepest automation when combined with its CRM ecosystem, though at higher price points. Brevo offers strong automation at budget-friendly pricing, making it ideal for companies implementing demand generation strategies without enterprise budgets. Constant Contact's automation remains basic even on premium tiers, limiting its utility for sophisticated B2B campaigns.

Are there reliable free email marketing platforms for early-stage B2B SaaS?

Several alternatives offer substantial free tiers: Brevo provides 300 emails daily with high contact limits on its free plan, MailerLite includes up to 1,000 contacts with 12,000 monthly emails, and HubSpot offers a free CRM and marketing tools that can store a large contact database (with paid tiers for marketing contacts). GetResponse’s free tier covers up to 500 contacts. Constant Contact offers a time-limited 30–60-day trial with no ongoing free option.

How can Genesys Growth help evaluate and implement email marketing alternatives?

Genesys Growth's consulting services provide hands-on platform selection and implementation support through weekly deliverable sprints. This includes tooling and stack audits, migration planning, automation workflow design, and integration with broader go-to-market architecture. The Fractional Plan specifically addresses cross-channel marketing strategy and agency partner management—ensuring email platform investments align with lifecycle marketing and content operations requirements.

What key considerations should B2B SaaS prioritize when selecting an email tool?

Five factors determine success: Automation depth must support multi-step nurture sequences for B2B sales cycles. CRM integration enables sales-marketing alignment without expensive add-ons. Pricing scalability should favor unlimited sends or email-based pricing over contact-based models that penalize growth. Deliverability rates directly impact campaign ROI—Constant Contact shows high deliverability in independent testing. Integration ecosystem matters for connecting with product analytics, billing systems, and sales tools that B2B SaaS companies require.

Beyond email, what GTM tools should integrate with my email platform?

Successful B2B SaaS stacks connect email marketing to CRM (HubSpot, Salesforce), product analytics (Amplitude, Mixpanel), customer success platforms (Intercom, Zendesk), and data enrichment tools. Genesys Growth's tools directory provides curated recommendations with exclusive deals. For companies pursuing product-led growth, integration with product usage data enables behavioral email triggers that alternatives like ActiveCampaign and HubSpot support natively—capabilities that Constant Contact lacks without expensive third-party connectors.
