The best Mailchimp alternatives for agencies in 2026
Short answer: Mailchimp is a strong email tool for a single business, but neither its pricing page nor its partner program offers the app under your own brand. ResellPortal is the alternative with no monthly platform fee, at $8 wholesale per client a month for 5,000 emails. Campaign Monitor suits agencies that want private labeling with billing built in, Elastic Email and BigMailer suit agencies that want the app on their own domain, and Sendy suits teams that self-host.
Most agencies meet Mailchimp first, because their clients already use it. They look for an alternative when they want to sell email marketing as their own product. Mailchimp's free plan now stops at 250 contacts and 500 sends a month, paid plans climb with list size, and its agency program, Mailchimp & Co, offers training, tools for managing several clients and commission. It does not put your name on the app. The alternatives below let you rebrand the app, set your own price, or both.

1ResellPortal
ResellPortal sells email marketing as a product in your own store. Each client gets an email app on your store's domain with your name on it. They send or schedule campaigns after a test send and spam check, run eight automation triggers, and start from 15 ready-made templates or an AI-built one. Eleven opt-in form styles grow their lists, and each campaign reports opens, clicks, bounces and unsubscribes. Emails go out from the client's own verified domain.
Wholesale is per sending tier: $8 a month for 5,000 emails, $25 for 25,000, $55 for 50,000 and $140 for 100,000, with suggested retail from $25 to $299. Clients pay your price into your own Stripe or PayPal. There is no platform fee: a $20 wallet, with a $10 bonus on a first deposit of $20 or more, covers wholesale as clients join. The trade-off: clients who expect to drag blocks around will miss a visual editor, since templates are HTML with a live preview or come from the AI builder.
2Campaign Monitor
Campaign Monitor is the hosted option closest to Mailchimp with real agency tooling. One admin account holds client sub-accounts, one dashboard shows them all, private labeling swaps Campaign Monitor's branding for yours, and its billing can add your markup and charge clients for you. Lite starts at $13 a month for 500 contacts.
3Elastic Email
Elastic Email pairs a marketing app with an email API. On its $49 Pro plan for 2,500 contacts, the interface can run on your own domain, SMTP and the HTTP API can be white-labeled, and sub accounts keep each client separate. It fits agencies that send for apps as well as newsletters.
4BigMailer
BigMailer targets agencies that juggle many brands. With white label on, the platform runs on your domain under your logo with every BigMailer mention removed, once you add DNS records it supplies. Plans start at $20 a month, priced per 5,000 contacts. BigMailer bills you for total usage, and you handle each client's billing and support.
5Sendy
Sendy costs $69 once and runs on your own web hosting with PHP and MySQL. Emails go out through Amazon SES at $1.60 per 10,000. Each client can be a brand with its own login, prices and sending limits. A license covers one domain, and keeping the server healthy and the emails landing is up to you.
6GoHighLevel
GoHighLevel's email and SMS tools, billed by usage, are one part of a CRM, funnel and automation suite. The suite costs $97, $297 or $497 a month, and only the $497 plan includes SaaS mode for reselling it as your own. It pays off when clients use the CRM and funnels too.
When Mailchimp is still the right choice
If you manage one business's email, or a client wants to own the account and see a brand they know, Mailchimp remains a sensible choice. Its free plan is enough to test with a small list, and paid plans remove the Mailchimp branding from emails. Agencies that would rather earn commission than run billing can join Mailchimp & Co for free. Choose an alternative when the app, the invoice and the client relationship should carry your name.
Common questions
Is there a white-label version of Mailchimp?
Not on Mailchimp's pricing or partner pages. Paid plans remove Mailchimp branding from the emails, but the app stays Mailchimp. ResellPortal, Campaign Monitor, Elastic Email and BigMailer all let clients work in an app under your brand.
What is the cheapest Mailchimp alternative an agency can resell?
ResellPortal has no platform fee and costs $8 a month wholesale per client for 5,000 emails, so an agency with one client pays $8. Sendy is a one-time $69 license plus Amazon SES sending, but you host and maintain it yourself.
Can I move a client's list from Mailchimp?
Yes. Export the contacts from Mailchimp as a CSV file and import it. On ResellPortal the client imports the CSV, sorts contacts into lists and tags, and verifies a sending domain with three CNAME records and one TXT record before the first send.
