Why Integrate External Email Marketing Software with HubSpot?

Before diving into specific tools, it's important to understand why businesses choose to integrate external email marketing platforms with HubSpot CRM:

• Cost Optimization: The starting price for the Marketing Hub Professional of HubSpot is $890 per month. This might be costly for small to medium-sized businesses. External email marketing applications may offer even better features at a significantly lower cost.

• Specialized Features: Certain businesses might have complex ecommerce, advanced deliverability, or other automation requirements that specialized email services can solve.

• User Experience: Some teams may prefer the user experience of specialized email marketing tools.

• Scalability: Some email tools allow you to scale with more flexible pricing structures and rates, whether with unlimited contacts or pay-by-volume pricing instead of pay-by-contact pricing.

Understanding HubSpot Integration Types

When evaluating email marketing tools for HubSpot integration, it's crucial to understand the different integration types:

• Native Two-Way Sync: Native integration into the HubSpot marketplace, where all contact and engagement data is synced by default both ways. Best for seamless setup with minimal maintenance.

• One-Way Sync: The data flow is only from HubSpot to the email platform, typically involving contacts and properties. It means the engagement data won't push back to HubSpot.

• Third-Party Integration Tools: Middleware platforms connect HubSpot with email tools and allow flexible data syncing. Often supports two-way sync, but at an additional cost.

• Data Sync in HubSpot Operations Hub: Native, enterprise-level two-way data sync within HubSpot. Reliable and real-time,e but requires an expensive plan.

Key Features to Look for in HubSpot-Compatible Email Marketing Software

• Contact Synchronization: The purpose here is to make sure contacts between HubSpot and the email service are properly synchronized for standard fields, custom properties, lifecycle statuses, lists, and preferences for opting out.

• Engagement Data Sync: The email engagement activities, such as opening, clicking, bouncing, and unsubscribing, can be synchronized back to HubSpot for improved lead scoring and sales follow-up.

• Segmentation Capabilities: Allows the execution of target marketing campaigns via HubSpot contact properties, lifecycle, website behaviors, or CRM Custom Segments.

• Automation Workflows: Provides support for triggered campaigns, including lead nurturing campaigns, cart abandonment campaigns, re-engagement campaigns, and behavior-triggered campaigns.

• Deliverability Features: Aids in ensuring landing in the inbox through authentication, bounce management, list hygiene solutions, and spam testing.

• Monitor Sync Health: Enables monitoring for sync log status, field mapping quality, API use, or duplicate contacts.

• Plan for Scale: Contemplates scaling support for handling a larger volume of contacts, a rise in API usage, and more frequent syncs.
