If your agency runs paid ads, SEO, or social — but bills email-marketing time hourly — you're leaving the easiest recurring revenue in the building on the table.
Every client has their own Mailchimp / Klaviyo / ConvertKit. Your team juggles seven logins, seven billing cycles, and seven different UI quirks. The hourly time spent context-switching is what your clients refuse to pay for — but you eat it anyway.
You bill $150/hr for the campaign you built. Client pays once, the work is done, you're back to selling the next month. There's no recurring email-marketing revenue line on your P&L — even though the work absolutely is recurring.
Mailchimp's “Agency Plan” doesn't exist as white-label. ActiveCampaign white-label kicks in only on Enterprise. Most ESPs gate the white-label bit behind their highest tier — making the agency play financially inaccessible until you already have the clients.
If you run all your clients off one shared sender pool and one of them runs a sketchy promo, the bot complaints from that client tank deliverability for every other client. Without sub-account isolation, one bad client can make every client suffer.
The Agency tier ships the SubAccount model. Spin up a new client account in three clicks — they get their own subscriber database, their own automations, their own segments, their own sending provider connections. Nothing crosses over. Your agency dashboard sees them all; each client sees only their own workspace.
Upload your light and dark logos. Pick your brand colors they apply across the dashboard, the email builder, the emails sent through the platform. Configure plan-based email footers per client. Run on your own domain. Clients log into app.youragency.com, not anything that says CleverlyBox.
The platform integrates with the SendGrid sub-account API via the SubAccountSendGrid model. Provision a fresh SendGrid sub-account for each client — they get their own dedicated IP pool (or shared pool, your call), their own warmup curve, their own complaint stats. One client running a sketchy promo can't drag everyone else's deliverability down.
Set quotas per sub-account on subscribers, monthly sends, lists, segments, automations, max process workers, max upload size. Build your own pricing tiers Starter $99/mo (10K subs, 50K sends), Growth $299/mo (50K subs, unlimited sends), Enterprise custom. The quota engine enforces the limits; the billing engine you bring (Stripe, Paddle, your invoice software) charges them.
The AdminGroup model gives you granular permission groups inside each sub-account. Junior copywriter can draft and preview campaigns but can't hit send. Account manager can send but can't change billing or sending providers. Client can log in to see analytics but can't change segments. Build the permission matrix that fits how your agency actually operates.
CleverlyBox costs you $149 once. What you charge clients is up to you.
Three pricing models that agencies on the platform are running today.
Charge a fixed $99/mo per client for “email marketing managed.” Includes platform access + 4 campaigns/mo + 1 automation. 20 clients × $99 = $1,980/mo recurring.
Build Starter / Growth / Enterprise tiers. Charge $99 / $299 / $799 per month. Quotas enforce the difference. Mix of 10 Starter, 8 Growth, 2 Ent = $4,980/mo recurring.
Charge $1,500 retainer for “email marketing on autopilot” — campaigns, automations, list health. Platform access bundled. 6 retainers × $1,500 = $9,000/mo recurring.
No revenue cap. No per-client surcharge. No “you must badge our logo.” The $149 Agency lifetime ships with full commercial-use rights — bill clients whatever you want, keep 100% of the revenue, white-label the whole experience under your brand. The license is yours, lifetime.
Most agencies inherit a stack of client Mailchimp / Klaviyo / ConvertKit logins they didn't pick. Here's the four-step migration playbook agencies on CleverlyBox follow.
From the agency dashboard, create one sub-account per client. Apply your Starter / Growth / Enterprise quota template. Set the SendGrid sub-account or sending provider — their own SES, your shared pool, or fresh dedicated. 5 minutes per client.
Export each client's subscriber CSV from their existing ESP. Run it through CleverlyBox verification built-in, 14 providers — catches inactive contacts the old ESP was billing for. Import the verified list into the sub-account. Often saves the client more than your monthly fee.
Recreate the welcome sequence, the cart-abandon flow, the re-engagement automation. Use the AI copywriter to draft new subject lines while you're at it — fresh creative without paying a copywriter. Saved prompts carry house-style across all clients.
Update signup form endpoints. Point any third-party integrations like Stripe, Shopify, or e-commerce platform at the CleverlyBox webhook. Send the first campaign through the new sub-account. After 30 days of healthy sending, downgrade or cancel the old ESP — savings hit your client's P&L the next billing cycle.
