Agency evaluation checklist
| Client separation | Check roles, workspaces, billing, sender domains, approvals, and whether an account can be handed back cleanly. |
|---|---|
| Reporting | Test exports, attribution windows, branding controls, and whether reports explain decisions rather than only display opens and clicks. |
| Delivery | Map consent, suppression, bounce handling, transactional streams, and domain ownership for every client. |
Mailchimp
Best for: Broad client ecosystem. Mailchimp is a practical Campaign Monitor alternative when clients need familiar integrations, forms, ecommerce connections, and a large template ecosystem.
Agency cost can change with contacts, archived records, seats, and account structure; model several client scenarios before standardizing.
| Pros | Cons |
|---|---|
| Broad integrations and recognition | Contact and account pricing complexity |
Pricing note: Free entry tier and contact plans; verify current pricing. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
MailerLite
Best for: Small clients that value simplicity. MailerLite works well for smaller client accounts where the agency needs newsletters, forms, landing pages, and basic automation with low training overhead.
Reporting, permissions, and advanced approval workflows may be lighter than Campaign Monitor, so test the agency handoff.
| Pros | Cons |
|---|---|
| Fast onboarding and accessible workflow | Less agency reporting depth |
Pricing note: Free tier and subscriber plans; verify limits. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Brevo
Best for: Marketing plus transactional delivery. Brevo suits agencies managing both promotional campaigns and transactional messages for clients that want fewer vendors.
Separate sender identities, consent purposes, and client workspaces carefully so transactional deliverability is not mixed with campaign operations.
| Pros | Cons |
|---|---|
| Broad email coverage | Different collaboration model |
Pricing note: Free tier and usage plans; verify current limits. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
HubSpot
Best for: Campaigns tied to CRM and sales. HubSpot is the stronger option when an agency’s reporting must connect campaigns to pipeline, owners, forms, and customer lifecycle stages.
It brings more implementation and governance work; define client data ownership before building shared workflows.
| Pros | Cons |
|---|---|
| CRM attribution and team visibility | Broader platform overhead |
Pricing note: Free tools exist; paid hubs and contacts vary. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
ActiveCampaign
Best for: Complex nurture and lead scoring. ActiveCampaign fits clients who need conditional nurture, scoring, and sales handoffs beyond polished broadcasts.
Its flexibility creates maintenance overhead, so agencies need naming standards, reusable templates, and an automation inventory.
| Pros | Cons |
|---|---|
| Detailed automation and scoring | More administration per account |
Pricing note: Contact and feature tiers; verify current pricing. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Klaviyo
Best for: Commerce-focused client programs. Klaviyo is a strong choice for ecommerce clients where browse, catalog, and purchase events shape campaigns and reporting.
It may be overbuilt for service businesses and requires reliable store data plus careful consent configuration.
| Pros | Cons |
|---|---|
| Commerce segmentation and revenue context | Poorer fit for non-commerce clients |
Pricing note: Usage-based; verify contacts and messages. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Customer.io
Best for: Behavioral lifecycle programs. Customer.io is useful when the agency manages product-led or SaaS accounts whose email depends on events rather than calendar campaigns.
Client onboarding requires event taxonomy, identity rules, and a clear developer handoff—very different from a template-first workflow.
| Pros | Cons |
|---|---|
| Deep event-driven automation | Higher technical setup |
Pricing note: Usage-based; verify workspace limits. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Kit
Best for: Creator and course clients. Kit is a sensible alternative for creators, educators, and coaches whose work centers on broadcasts, forms, and evergreen sequences.
Agency teams should confirm collaboration, client ownership, and commerce integrations before managing many accounts there.
| Pros | Cons |
|---|---|
| Creator-oriented sequences | Narrower agency operations |
Pricing note: Free and paid subscriber plans; verify features. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
beehiiv
Best for: Publication and newsletter growth. beehiiv fits media and newsletter clients that prioritize publication workflows, referrals, recommendations, and growth analytics.
It is less general-purpose for CRM campaigns and client-specific automation, so clarify the publication operating model first.
| Pros | Cons |
|---|---|
| Newsletter growth tooling | Less broad marketing automation |
Pricing note: Free and paid plans; verify subscriber limits. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
SendGrid
Best for: API and transactional-heavy clients. SendGrid is appropriate when a client needs dependable API delivery alongside a marketing layer and the agency has technical support.
The agency may need to own template versioning, event orchestration, suppression, and deliverability operations.
| Pros | Cons |
|---|---|
| Established API ecosystem | More custom implementation |
Pricing note: Free tier and tiered plans; verify volume pricing. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Resend
Best for: Developer-led product teams. Resend fits product clients whose developers own event logic and want a clean API-first sending workflow.
It does not replace agency campaign planning, audience operations, or reporting without an additional system.
| Pros | Cons |
|---|---|
| Modern developer workflow | Limited marketer-facing automation |
Pricing note: Usage-based; verify current limits. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Postmark
Best for: Critical transactional streams. Postmark is a focused choice for client applications where inbox placement and separation of transactional streams matter most.
Use it for operational delivery, not as a full replacement for campaign production and nurture.
| Pros | Cons |
|---|---|
| Focused transactional delivery | Limited campaign breadth |
Pricing note: Usage-based message plans; verify pricing. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Drip
Best for: Smaller ecommerce clients. Drip is useful for ecommerce clients that need customer behavior and purchase history to drive repeat-purchase campaigns.
Compare agency access, reporting exports, and integrations before using it as a standard across clients.
| Pros | Cons |
|---|---|
| Commerce lifecycle focus | Narrower general-purpose workflow |
Pricing note: Subscriber-based plans; verify current tiers. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
EmailOctopus
Best for: Cost-conscious client newsletters. EmailOctopus can fit small clients whose needs are broadcasts, forms, and basic sequences at a predictable starting cost.
Validate integrations, reporting, and permissions when the agency’s service includes performance analysis or complex automation.
| Pros | Cons |
|---|---|
| Lean and accessible workflow | Less depth for advanced clients |
Pricing note: Free tier and subscriber plans; verify limits. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Amazon SES
Best for: High-volume infrastructure projects. SES is worth considering when an agency supports a technical client that needs AWS-native delivery control and custom sending economics.
The agency must account for bounce processing, suppression, templates, monitoring, and the entire marketer-facing layer.
| Pros | Cons |
|---|---|
| Control and low-level cost | Most workflow features are external |
Pricing note: Usage-based AWS pricing; verify quotas. Confirm current account, contact, send, seat, and agency-access rules on the official vendor page.
Migration checklist for agencies
- Inventory client domains, consent, templates, suppressions, integrations, and reporting promises.
- Build one reusable but client-safe template system without sharing audience data across accounts.
- Test approval, rollback, unsubscribe, bounce, and client handoff paths.
- Compare total account management time—not just sending price—before standardizing the platform.
