Marketo
Marketo, a B2B marketing automation platform from Adobe, stands out for businesses seeking robust marketing automation without the AI focus of HubSpot Marketing Hub. Unlike Systeme.io and ActiveCampaign, Marketo does not offer a free tier or self-serve signup, appealing to larger enterprises that prioritize comprehensive automation over cost. It shares three capabilities with HubSpot, making it a strong contender for those focused on marketing automation.
