The best white-label email marketing platforms in 2026

A white-label email marketing platform lets you give clients campaigns, lists and automations in an app with your name on it. Some are hosted platforms with agency features, some are self-hosted software you install and brand yourself, and some are reseller platforms where each client is a sale. The seven below are the ones agencies and resellers compare most in 2026.

Quick comparison

1ResellPortal

ResellPortal's Email Marketing gives your clients campaigns with test sends and a spam score check, automations with eight triggers, AI-built templates plus 15 ready-made ones, 11 opt-in form styles, contact lists and a full report for every campaign. Emails go out from the client's own verified domain, and the app runs on your store's domain under your brand. 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.

There is no monthly platform fee: you fund a wallet (the minimum is $20, and a first deposit of $20 or more gets a $10 bonus) and clients pay you directly through your own Stripe or PayPal. The trade-off: there is no drag-and-drop editor, as templates are edited in HTML with a live preview or built by AI, and clients must verify their sending domain before they send.

2Campaign Monitor

Campaign Monitor is a hosted email platform with a dedicated set of agency features: sub-accounts under one admin account, a dashboard across all client accounts, private labeling that replaces Campaign Monitor branding with yours, and billing that adds your markup and bills clients for you. Lite starts at $13 a month for 500 contacts, and prices rise with list size.

3Elastic Email

Elastic Email offers email marketing and an email API. Its Pro plan, $49 a month at 2,500 contacts, includes reseller and custom branding features: the interface on your own domain, white-label SMTP and HTTP API, and sub accounts with user management. It suits resellers who want sending infrastructure as well as a marketing app.

4BigMailer

BigMailer is an email platform for agencies managing many brands. Its white label hosts the platform on your own domain with your logo and all BigMailer references removed, set up by BigMailer through DNS records. Paid plans start at $20 a month and are priced per 5,000 contacts. BigMailer bills you on total usage, so billing and support for your clients are yours to run.

5GoHighLevel

GoHighLevel includes email and SMS marketing, billed by usage, inside its CRM and funnel suite. Plans are $97, $297 and $497 a month, and SaaS mode for reselling the suite under your brand is on the $497 plan. It is a lot of software if email is all your clients need.

6Sendy

Sendy is a self-hosted newsletter app with a one-time $69 license. It runs on your own PHP and MySQL hosting and sends through Amazon SES at $1.60 per 10,000 emails. You can group clients into brands, give them access, set their pricing and sending limits, and use custom domains for links. Each license covers one domain, and you run the server yourself.

7MailWizz

MailWizz is self-hosted email marketing software you install on your own server. The Extended license is the one required to run it as a SaaS business, with unlimited customers, groups and price plans. Licenses are sold as yearly subscriptions or lifetime licenses, and each includes 1 month of premium support. It suits developers who want to build their own email service.

Common questions

What is white-label email marketing software?

It is an email marketing platform you sell or give to clients under your own brand. Clients build campaigns, manage lists and see results in an app with your name on it, and you set the price.

Is there a white-label Mailchimp alternative?

Yes. ResellPortal's Email Marketing is a branded alternative you resell from $8 a month wholesale per client, with campaigns, automations, AI templates and opt-in forms. Campaign Monitor and BigMailer also offer private labeling for agencies.

Can I resell email marketing under my own brand?

Yes. On ResellPortal you switch on Email Marketing and set your retail price, and clients buy on your storefront and pay you directly. Your wallet pays only the wholesale price for each client's sending tier, from $8 for 5,000 emails a month to $140 for 100,000.

Do clients need to verify a domain to send?

On ResellPortal, yes. They add three CNAME records and one TXT record at their DNS provider, and the app checks them. Sending from a verified domain helps emails reach the inbox.
