Ratings & Reviews
Who Should Choose Which?
You are a solo founder or nonprofit staffer launching your first email campaign on a tight budget. You need to test whether email marketing drives engagement before committing funds. Mailchimp's free tier lets you manage up to 250 contacts and send 500 emails monthly at no cost, with access to basic templates and email support during your first 30 days. Once you're ready to scale, the Growth plan ($20/month) unlocks automation flows, dynamic content, and predictive segmentationΓÇöall critical for personalized outreach. Constant Contact's $20 entry point forces an immediate financial commitment that may not suit early-stage validation.
You are a marketing manager at a growing service-based firm with 500ΓÇô1,000 contacts and a need for straightforward campaign creation without complex automation. Constant Contact's Starter plan ($12/month) and Growth plan ($35/month) offer drag-and-drop simplicity and social posting that your team can master quickly. The interface prioritizes ease over feature depth, which reduces onboarding friction. However, if your team later needs advanced segmentation, multivariate testing, or sophisticated automation workflows, Mailchimp's Standard and Premium tiers provide those capabilities at comparable or lower price points. Constant Contact's limited automation templates may feel restrictive as your campaigns grow more sophisticated.
Bottom Line
Mailchimp is the better choice for budget-conscious teams and those requiring advanced automation at scale.

Frequently Asked Questions
-
Is Constant Contact better than Mailchimp?

-
How do Constant Contact and Mailchimp pricing compare for growing businesses?
Mailchimp's pricing structure scales more gradually with contact growth, starting free and reaching $350/month at 10,000 contacts. Constant Contact charges a flat $20ΓÇô$80/month regardless of contact count, making it predictable but less flexible for rapid scaling. For a business with 5,000 contacts, Mailchimp's Growth plan ($20/month) costs significantly less than Constant Contact's Pro tier ($80/month). However, Mailchimp's SMS add-on and transactional email features carry separate charges, while Constant Contact bundles 500 SMS/month into its Pro plan. Choose Mailchimp if contact growth is unpredictable; choose Constant Contact if you prefer fixed monthly costs.
-
What are the main feature differences between Mailchimp and Constant Contact?
Mailchimp offers multivariate testing (up to 8 variants) on its Premium plan, while Constant Contact limits A/B testing to subject lines only on Standard+. Mailchimp includes a native landing page builder across all paid tiers; Constant Contact does not list this as a core feature. Mailchimp's automation workflows support up to 200 steps with branching on Standard and Premium, whereas Constant Contact caps custom automations at unlimited only on its Pro plan. Mailchimp also provides transactional email via a paid add-on, a capability Constant Contact lacks entirely. Both tools offer drag-and-drop editors and SMS add-ons, but Mailchimp's broader feature depth makes it stronger for teams planning to scale beyond basic email campaigns.
-
How difficult is it to migrate from Constant Contact to Mailchimp?
Migration from Constant Contact to Mailchimp is straightforward. Both platforms support CSV export and import, allowing you to transfer your contact lists without data loss. Mailchimp accepts standard CSV files and can map your existing fields during import. Email templates and automation workflows must be recreated manually, as neither platform offers direct template migration. The process typically takes a few hours for small lists under 5,000 contacts. Mailchimp's support team can assist with the import process if you encounter issues. Plan for one to two weeks of parallel running both systems to ensure all data transfers correctly before fully switching.
-
Which tool offers better integrations and customer support?
Mailchimp provides superior support infrastructure with 24/7 email and chat support on paid plans, plus a dedicated onboarding specialist on the Pro tier. Both tools offer 300+ integrations, but Mailchimp's native ecommerce connectors (Shopify, WooCommerce, Squarespace Commerce) are more robust, with built-in purchase-triggered automations and revenue attribution. Constant Contact requires Zapier for WooCommerce integration. For customer support, Mailchimp's tiered approach ensures growing teams receive escalating assistance, while Constant Contact's support quality is noted positively by users but lacks the dedicated specialist option available at higher Mailchimp tiers.
