At 5,000 contacts, you’d pay $39/month on Sender Standard and $75 on Mailchimp Essentials. Part of that gap is Mailchimp pricing itself: on Mailchimp plans, non-subscribed and unsubscribed contacts still land on your bill. Sender only counts unique, active subscribers. And the Mailchimp free plan? It tops out at 250 contacts.
*Mailchimp charges $26.50 for its 501–1,500-contact tier. Therefore, an account with 1,000 contacts pays for the 1,500-contact tier.
**Sender’s 30% discount applies to the first year of annual billing. After the first year, annual plans continue at 20% off.

When Sender is the better fit
Pick Sender if you've hit Mailchimp's 250-contact ceiling and want a more generous free plan with transactional email included. Looking for a Mailchimp alternative for Shopify or WooCommerce? Ecommerce brands get longer automation workflows and 24/7 support on one plan. Mostly sending newsletters? It's a Mailchimp alternative for newsletters that won't bill you for readers who've left. At 10,000 contacts, that's $69 a month compared to Mailchimp's $110.
When Mailchimp may be the better fit
Native Mailchimp integrations are where it outshines Sender. Its integration marketplace is bigger, and it plugs straight into Intuit products like QuickBooks. With Mailchimp Standard, you get predictive segmentation and send-time optimization; Mailchimp Premium adds multivariate testing. It also bundles a website builder, appointment booking, and a built-in CRM. Sender has none of those.

Customer service was great. I needed help with setting up DNS records for emails. My rep stayed in the chat with me for the entire time until the issue was handled. So happy with the service.
A first class experience from the customer service team who take the time and effort to assist until the issue is resolved.
Fantastic customer support and very quick response times. My account review was handled professionally and efficiently, and I really appreciate Sender.net's strong focus on anti-spam and responsible email practices.
I would like to express my sincere appreciation for the outstanding service I received from Malissa. Throughout our interaction, she was exceptionally patient, highly professional, and consistently helpful. Her deep product knowledge made it easy to understand each step, and she guided me through every challenge with clarity and confidence.
If you're after an alternative for small businesses that send newsletters and automated emails, yes. Sender costs $39 a month at 5,000 subscribers; Mailchimp Essentials costs $75. Whether it's the best Mailchimp alternative for you depends on your needs. Like other Mailchimp competitors, Sender won't match every need, so check your must-haves before you switch.
Plenty of free alternatives exist, but most free plans are tight. Mailchimp's own gives you 250 contacts and 500 monthly emails. Sender free plan gives you 2,500 subscribers and 15,000 monthly emails, with automation included and no credit card required. If you're after the best free Mailchimp alternative for more than basic email marketing, that's ten times the room.
At every list size, Sender pricing wins. A 1,000-contact list costs $15/month on Sender Standard. On Mailchimp Essentials, it's $26.50, because 1,000 contacts falls into the 1,500-contact tier. At 10,000 contacts, it's $69 versus $110. Paying yearly? Sender also offers a 30% annual discount for the first year; Mailchimp offers 15% off for 12 months, and only on 10,000+ contacts.
Yes, and it catches a lot of people out. Mailchimp unsubscribed contacts count toward your bill, and so do non-subscribed contacts, like one-time buyers synced from your online store. Cleaned, deleted, and archived contacts don't, which is why archiving becomes a monthly chore. Unlike Mailchimp, Sender’s billable contacts are active and unique only.
It does, minus the step counter. Mailchimp Essentials has a four-step automation limit, which is where a Mailchimp automation alternative earns its keep. Sender's visual automation builder has no step limit, and yes/no branching works on every plan, Free included. Automated workflows can start from opens, clicks, abandoned carts, or custom events your app sends via API.
Yes, on every plan, from the same account as your campaigns. Order confirmations, password resets, and other transactional emails go out through SMTP relay or the REST API. Mailchimp hands that job to Mailchimp Transactional (the old Mandrill), a paid add-on you can't use with Essentials. As a Mailchimp transactional email alternative, Sender saves you a second bill and login.
