Frequently Asked Questions about best email sequencing software for agencies
Agencies should prioritize automation capabilities that allow sequences to trigger based on contact behavior, multi-channel integration (email plus SMS or calls), detailed engagement tracking that shows which prospects opened emails and clicked links, and team collaboration features allowing multiple team members to manage client sequences. Additionally, look for customizable templates to maintain client branding, integration with your existing CRM or tech stack to avoid manual data entry, and reporting that shows sequence performance metrics. For agencies managing multiple client accounts, the ability to segment audiences and personalize content at scale is critical. Finally, prioritize platforms offering API access for custom integrations with client systems, as this eliminates manual data syncing.
All-in-one platforms like HubSpot Sales Hub or Salesforce work best when you need CRM, deal management, and reporting alongside email sequencing. They reduce tool switching and keep all customer data in one system. Specialized tools like Klaviyo or Streak are better when you only need robust email automation and want to keep existing CRM or other systems. Consider your team size: smaller agencies (under 10 people) often work better with specialized tools, while growing agencies (20+ people) benefit from all-in-one platforms that provide shared visibility across the sales pipeline. Also factor in integrations—if you already use HubSpot or Salesforce, adding their native sequencing is simpler than integrating a third-party tool. Finally, consider budget: specialized tools are usually cheaper per user, while all-in-one platforms cost more but reduce the total number of systems to manage.
Email sequences are typically one-to-one outreach sent to individual prospects or leads, often used in sales outreach with messages like 'Hi [Name], following up on our earlier conversation.' Email marketing automation targets groups of contacts based on behavior and sends campaigns to segments—for example, 'send all website visitors who viewed pricing a discount email.' Sales teams typically use sequences for prospecting; marketing teams use automation for nurturing. Platforms like HubSpot and Zoho handle both, while Klaviyo specializes in marketing automation. Choose based on your primary need: if your agency's clients primarily do B2B sales prospecting, prioritize sequence features. If clients are e-commerce or SaaS companies doing nurturing campaigns, prioritize marketing automation with segmentation and dynamic content.
Costs range from free (basic Slack Sales Elevate or Notion CRM) to $100+ per user monthly for enterprise platforms. Most agencies spend $15-50 per user monthly for dedicated tools like Streak, Copper, or Zoho. If choosing an all-in-one platform like HubSpot or Salesforce, add $45-165 per user monthly. Calculate total cost by multiplying per-user price by your team size. For a 10-person agency, expect $150-500 monthly for a specialized tool or $500-2,000+ for an all-in-one platform. Budget-conscious agencies often start with affordable tools like Zoho ($18/user) or Streak ($15/user), then upgrade to all-in-one platforms as they grow. Remember to factor in implementation time, training, and potential integration costs when comparing platforms, as the cheapest tool isn't always the lowest total cost of ownership.
Conclusion
Choosing the right email sequencing software depends on your agency's size, budget, and current tech stack. For established agencies wanting a complete solution, HubSpot Sales Hub combines powerful email automation with full CRM capabilities, though it requires the highest investment. Cost-conscious agencies should evaluate Zoho CRM or Streak, which deliver solid sequencing features at $15-35 per user monthly. If your team operates entirely within Gmail, Copper or Streak eliminate context switching by managing sequences directly in your inbox. For agencies managing both calls and emails, Aircall provides valuable integration that prevents constant tool switching. Consider HubSpot Sequences if you want HubSpot's quality without full Sales Hub pricing, or Klaviyo if your clients are primarily e-commerce or subscription businesses requiring sophisticated segmentation and personalization. Larger, more established agencies planning significant growth should evaluate Salesforce Essentials or Podio, both offering unlimited customization at the cost of longer implementation. The platform that works best isn't necessarily the most expensive—it's the one your team will actually use consistently. Test a few platforms during free trial periods, focus on adoption ease, and prioritize systems that integrate with your existing tools to avoid data silos. Many agencies start with specialized tools like Streak or Zoho and upgrade to all-in-one platforms as their needs become more complex. Whatever platform you choose, success depends on consistent execution of your sequences, not the software itself. If you want help implementing your chosen platform and designing effective sequences for your clients, services like RevAlign.io can provide expert guidance on strategy and best practices.
