Why Consider Campaign Monitor Alternatives?
Campaign Monitor is a reliable email tool, but agencies and growing businesses have compelling reasons to look elsewhere.
Pricing Structure
Campaign Monitor's per-contact model becomes expensive for agencies managing multiple large client lists. At scale, platforms with send-based pricing or flat rates offer better value.
Limited Automation
Campaign Monitor's automation capabilities are basic compared to ActiveCampaign or even Mailchimp. Agencies whose clients need complex journey automation quickly outgrow it.
Email-Only Focus
No native SMS, WhatsApp, or chat. As clients increasingly communicate on multiple channels, agencies need platforms that can grow beyond email alone.
No CRM Integration
Campaign Monitor does not include a CRM. Agencies managing client pipelines and sales alongside email must integrate or maintain a separate CRM tool, adding complexity.
Campaign Monitor Alternatives FAQ
Why do agencies switch away from Campaign Monitor?
The most common reasons are pricing and feature gaps. Campaign Monitor charges per email sent and per contact on paid plans, which can be expensive for agencies managing multiple large client lists. Additionally, Campaign Monitor's automation capabilities are more limited than platforms like ActiveCampaign, and it lacks multi-channel features (SMS, WhatsApp) that clients increasingly request. Agencies managing 5+ client accounts also find Campaign Monitor's multi-account management less flexible than alternatives.
What is the best Campaign Monitor alternative for agencies managing multiple clients?
Brevo is the strongest agency swap if your clients have large contact lists you email infrequently — send-based pricing keeps costs predictable regardless of stored contacts. ActiveCampaign is best for agencies delivering advanced automation and CRM services. Mailchimp is the safest swap if your clients are already familiar with the email marketing category. Dewx is the best choice if you want to consolidate client communication management beyond email into one platform.
Does Campaign Monitor have white-label options for agencies?
Campaign Monitor does offer an agency program with client sub-accounts. However, Brevo has stronger sub-account and white-label capabilities for agencies wanting to resell email marketing under their own brand. ActiveCampaign's agency partner program also offers volume discounts and consolidated billing useful for multi-client management.
Can I migrate my Campaign Monitor templates to another platform?
Campaign Monitor uses a drag-and-drop editor and its own template format. You can export email designs as HTML from most accounts, which can then be imported into platforms that accept custom HTML templates — including ActiveCampaign, Brevo, and Mailchimp. However, template fidelity may vary and some adjustment is typically needed. Contact migration (CSV export/import) is straightforward across all alternatives.
Is Dewx suitable for agencies replacing Campaign Monitor?
Dewx is ideal for agencies that want to manage client communications across multiple channels — not just email — from a single platform. Where Campaign Monitor handles email campaigns, Dewx also gives you a unified inbox for WhatsApp, LinkedIn, Gmail, and Instagram, plus a CRM and AI assistant. If your agency is managing client relationships across many touchpoints, Dewx significantly reduces the tool stack. For pure email campaign delivery at scale, Brevo or ActiveCampaign are more specialized.
