Frequently Asked Questions
Is Mailchimp still worth using in 2026?
Yes — for the right use case. Mailchimp is still the best choice for beginners, small service businesses, bloggers, and anyone who just needs to send a regular newsletter without complex automation. Its free plan (500 contacts), beautiful templates, and ease of use make it hard to beat for simple email marketing. However, if you need advanced automation or run an ecommerce store, tools like ActiveCampaign or Klaviyo will give you significantly better results.
Why is Klaviyo so popular with Shopify stores?
Klaviyo was built specifically for ecommerce from the ground up. It connects directly to Shopify and pulls in real-time data — product views, cart actions, purchases, and refunds — and uses that data to trigger highly personalized automated emails. Features like abandoned cart recovery, browse abandonment flows, AI product recommendations, and per-campaign revenue attribution are all native to Klaviyo. No other platform matches its depth for Shopify-first businesses.
What makes ActiveCampaign better than Mailchimp for automation?
ActiveCampaign has over 135 automation triggers compared to Mailchimp's roughly 15. It supports conditional logic, behavioral triggers (page visits, link clicks, purchase history), lead scoring, and multi-branch workflows that Mailchimp simply cannot match. It also includes a built-in CRM so your sales and marketing data stay in sync. For businesses where email automation is a core part of the sales process, ActiveCampaign is in a completely different league.
Which email marketing tool is cheapest for a large list?
At small list sizes (under 5,000 contacts) Mailchimp and ActiveCampaign are comparable in price. At larger lists (10,000+), ActiveCampaign becomes more expensive than Klaviyo on a per-contact basis. Mailchimp stays competitive up to around 50,000 contacts. For very large lists, Mailchimp or Klaviyo typically offer better value than ActiveCampaign's Plus plan, which charges $699/month for 50,000 contacts.
Can I use Klaviyo if I don't have a Shopify store?
Technically yes, but it is not recommended. Klaviyo's most powerful features — browse abandonment, purchase-triggered flows, predictive replenishment, and revenue attribution — only work with a connected ecommerce data source. Non-ecommerce users on Klaviyo end up paying a premium price for a platform they can only use at a fraction of its capability. For non-ecommerce businesses, Mailchimp or ActiveCampaign offer equal or better value.
Does ActiveCampaign include SMS marketing?
Yes, but SMS is a paid add-on — it is not included in the base subscription price. You buy SMS credits separately on top of your monthly plan. This is different from Klaviyo, which includes SMS natively in its paid plans. If SMS is a major marketing channel for your business, Klaviyo's all-in-one pricing may work out cheaper than adding SMS credits on top of an ActiveCampaign subscription.
