Is Mailchimp still the best email marketing tool?
Mailchimp remains one of the most popular email marketing platforms, particularly for small businesses and beginners. However, it is not necessarily the best for every use case. ActiveCampaign offers superior automation, Klaviyo is better for e-commerce, and ConvertKit serves creators more effectively. Mailchimp excels in ease of use and broad feature coverage.
Can email marketing software integrate with my CRM?
Most modern email marketing platforms offer CRM integrations. HubSpot has a built-in CRM. ActiveCampaign includes CRM functionality at its Plus tier and above. Mailchimp, Klaviyo, and ConvertKit integrate with popular CRMs including Salesforce, HubSpot, and Zoho. Klaviyo’s e-commerce integrations are the most extensive for online stores.

Email marketing focuses on creating and sending email campaigns, newsletters, and automated email sequences.
