Standout Differences
SendPulse's free tier includes a CRM
With SendPulse, the free tier allows sending as many as 15,000 emails monthly and throws in basic CRM and automation tools — a more generous starting point than Constant Contact, which offers only a time-limited trial and no lasting free option.
SendPulse
HubSpot's unified data model
HubSpot's free CRM underpins Marketing, Sales, and Service Hubs so every team works from the same contact record, a level of platform integration neither Constant Contact nor SendPulse documents.
HubSpot
Constant Contact leans on decades of support experience
Founded in 1995, Constant Contact emphasizes extensive live customer support and out-of-the-box automation for common small-business scenarios like abandoned-cart reminders and welcome series.
Constant Contact
SendPulse adds chatbots and an LMS
SendPulse's chatbot builder for WhatsApp, Instagram, Telegram, and Facebook Messenger, plus a course and LMS builder, extend it well beyond a typical email service provider, capabilities not documented for Constant Contact or HubSpot.
SendPulse
HubSpot's pricing ceiling is the highest
HubSpot's Enterprise tier can run from about $150 per seat per month up to $3,600+ per month for a bundled Customer Platform, well above SendPulse's pay-as-you-go pricing and Constant Contact's $80/month Premium plan.
