Agencies have a specific set of demands that most solo-user or small-business email tools weren’t built to address: managing campaigns across multiple clients, controlling costs as lists grow, delivering professional results under client branding, and ideally doing it all without juggling a dozen separate platforms. This guide looks at ten tools through that lens — what each one captures, what it costs, and where the friction tends to show up.
One honest upfront note: HubSpot’s feature data wasn’t captured in this round (the features page was skipped), so its section covers pricing and positioning signals only.

The Tools, One by One
GetResponse
GetResponse positions itself around AI-driven emails, automation, landing pages, and ecommerce tools. On the feature side, the captured list is genuinely broad for an email-first tool: an AI email generator, AI campaign generator, AI writing assistant, visual workflow builder, marketing automation, send-time optimization, newsletter templates, web push notifications, SMS marketing, popups and forms, live chats, ecommerce integrations, A/B testing, AI landing pages, and an AI website builder — plus a conversion funnel feature and paid ads capability. For agencies looking to consolidate more of their client work under one roof, that range covers a lot of ground without leaving email entirely.
Pricing runs from $15.58/month (billed annually) on the Starter plan up to $59/month (billed monthly) on the Marketer plan and $69/month (billed monthly) on the Creator plan. An Enterprise tier exists but is quote-only — contact their sales team for that pricing.
Some users report friction around invoicing and payments, and price-to-value concerns show up in reviews too — worth factoring in when pitching a tool to cost-conscious clients.
Moosend
Moosend’s captured features include email marketing, transactional emails, marketing automation, email marketing AI, landing pages, subscription forms, audience management, and reporting and analytics. There’s also a dedicated Agency Program listed in the feature data — a concrete signal that the platform has thought about agencies specifically, not just individual marketers.
Pricing is straightforward: a single Pro plan at $9/month billed monthly (with a promotional rate of $7/month also captured). That simplicity is either a feature or a limitation depending on your needs.
The review picture here is the most varied of any tool in this roundup: some users report friction with customer support, ease of use, reliability and bugs, invoicing and payments, and price/value. That’s worth a careful look during any trial period.
HubSpot
HubSpot’s Marketing Hub spans a wide price band: $20/month (billed monthly, 1 seat and 1,000 contacts included) at the entry level — with a promotional rate of $10/month also captured — up to $890/month (3 seats, 2,000 contacts included) at the Professional tier and $3,600/month (5 seats, 10,000 contacts included, billed annually) at Enterprise. The pricing structure scales with seats and contacts, so agency costs can rise quickly as client roster and list sizes grow.
Because the features page wasn’t captured in this round, we can’t describe what the platform does at the feature level beyond what’s in its pricing note. For a full feature picture, check HubSpot’s site directly. We also don’t have third-party review data for HubSpot in this dataset.
ConvertKit (Kit)
Now operating as Kit, ConvertKit positions itself around creators: the captured features include email marketing, visual automations, landing pages, an email designer, analytics, subscriber signals, paid newsletter support, newsletter sponsorships, course creator tools, paid recommendations, and a Kit App Store. There’s also a free migrations offering captured.
Pricing starts at $0/month (Free plan), moves to $33/month (Creator), and reaches $66/month (Pro), all billed monthly.
Some users report friction around customer support, ease of use, features and functionality, invoicing and payments, and price/value — a fairly wide spread of themes that agencies should probe in a trial before committing client accounts.
Mailchimp
Mailchimp’s captured features span email marketing, SMS marketing, AI marketing tools, marketing automations, content creation tools, social media marketing, reporting and analytics, a lead generation platform, audience management tools, transactional email, A/B testing, marketing automation flows, an email builder, dynamic content, generative AI, a subject line helper, behavioral targeting, a marketing CRM, and predictive demographics. The positioning explicitly notes the platform serves “businesses of all sizes.”
Pricing is contact-scaled. Entry points: $0/month (up to 250 contacts, Free), $13/month from 500 contacts (Essentials), $20/month from 500 contacts (Standard), and $350/month from 10,000 contacts (Premium). Agencies managing large client lists should note that Premium is not sold below 10,000 contacts.
Some users report friction with customer support, ease of use, invoicing and payments, and reliability and bugs — recurring themes across many email platforms but worth noting given agency reliance on uptime.
EmailOctopus
EmailOctopus’s captured positioning is “Email Marketing Made Easy,” and the captured feature items include forms and landing pages. Beyond that, the feature capture is limited — the data surfaces category pages and comparison pages rather than a detailed feature list, so the full capability picture isn’t available from this data alone.
Pricing is among the lowest captured here: a free Starter plan ($0, billed annually) and a Pro plan at $9, billed annually. For agencies managing tight budgets on smaller client accounts, that entry cost is notable.
Some users report friction with ease of use, customer support, invoicing and payments, and price/value.
beehiiv
beehiiv positions itself for “serious builders” and its captured feature items describe: launching a fully-custom newsletter designed to match your brand, creating a website to engage and grow an audience, scaling subscribers with built-in growth tools, monetizing with paid subscriptions and a native ad network, and tracking clicks, engagement, and key metrics from a centralized dashboard. The captured feature data also notes support for multiple newsletters.
Pricing: Launch plan at $0 (billed annually), Scale at $43/month (billed annually), Max at $96/month (billed annually), and an Enterprise tier that requires contacting sales.
Some users report friction around price/value, invoicing and payments, ease of use, customer support, and features and functionality.
AWeber
AWeber’s captured positioning centers on small business email marketing. Captured features include email marketing, email automation, a landing page builder, web push notifications, an AI signup form builder, an AI writing assistant, a link in bio page, pre-written email campaigns, app integrations, and an AWeber Certified Experts program. The feature data also notes “free account migration service” and “Contact Customer Solutions 24/7.”
Pricing is structured by subscriber count with three plans captured at the 0–500 subscriber tier: Lite at $12.49/month (billed annually), Plus at $19.99/month (billed annually), and Done For You at $20/month (billed annually).
Some users report friction with ease of use, invoicing and payments, and the mobile app.
Systeme.io
Systeme.io’s positioning is explicitly broad: “all the tools you need under the same roof” for running a business online. The captured feature categories include: creating sales funnels, sending marketing emails, building websites, managing affiliates, creating online courses, automating marketing, automating bookings, building a community, managing sub-accounts, selling physical products, SMS marketing, managing pipelines, running automated webinars, launching a creator store, and white-labeling systeme.io under your own brand.
That last item — white-labeling — is a direct agency signal. The sub-accounts management category is similarly relevant for agencies running multiple client environments.
Pricing: Free ($0, billed annually), Startup ($17/month, billed annually), Webinar ($47/month, billed annually), and Unlimited ($97/month, billed annually).
Reviews we scanned didn’t surface any recurring complaint pattern — no complaints found doesn’t mean everything is perfect, just that nothing repeated itself enough to flag.
HighLevel
HighLevel’s pricing plan names themselves signal agency intent: Starter at $97/month (billed monthly), Unlimited at $297/month (billed monthly), and Agency Pro at $497/month (billed monthly). The positioning and plan structure point toward agencies managing multiple clients.
The caveat: HighLevel’s feature page returned very limited detail in our capture (the page appears JS-rendered, with fuller detail on sub-pages). The captured categories list only “Affiliates” and “Events” — so we can’t describe the platform’s capabilities from this data. Check the site directly for a full feature breakdown before making any decisions.

Best-For Picks for Agencies
Best for Agencies That Want White-Label and Sub-Account Management
Systeme.io is the only tool in this dataset with both “White label systeme.io under your own brand” and “Manage your sub-accounts” explicitly captured as feature categories — the two things agencies most commonly ask for. It also has a transparent price ceiling of $97/month (billed annually) on the Unlimited plan, which makes client-by-client cost modeling straightforward.
Best for Agencies Managing a Dedicated Agency Program
Moosend is the only tool with an explicit “Agency Program” listed in its captured features. Combined with a $9/month (or $7/month promotional) entry price, it’s worth evaluating for agencies that want a program structure rather than a generic seat arrangement — just go in aware of the mixed review signals.
Best for Full-Stack Multichannel Campaigns
GetResponse has the broadest captured feature set in this group, spanning AI email generation, automation, SMS marketing, web push notifications, landing pages, an AI website builder, conversion funnels, ecommerce integrations, popups, live chats, paid ads, and A/B testing — all product-wide. For agencies that need to offer clients a wide channel mix from one platform, the range is hard to match in this dataset. Pricing runs from $15.58/month (billed annually) to $69/month (billed monthly) on published plans.
Best for Agencies with High-Volume Client Lists and Big Budgets
HubSpot has the highest published pricing ceiling of any tool here — $3,600/month for the Enterprise tier (5 seats, 10,000 contacts, billed annually) — and a correspondingly broad enterprise-grade positioning. Agencies already operating in HubSpot’s ecosystem and managing large contact volumes have the clearest path to that tier. Just know that features weren’t captured in this round, so confirm current capabilities on their site before committing.
Best for Cost-Sensitive Agencies Testing the Waters
EmailOctopus at $0 (Starter, billed annually) or $9 (Pro, billed annually) is the lowest-cost paid entry point in this dataset. If an agency is managing smaller client accounts on tight margins, the price floor is meaningful — though the feature capture here was thin, so a hands-on trial is essential before drawing conclusions.
The Bottom Line
No single tool here is a perfect agency fit out of the box — the right choice depends on which specific capabilities matter most to your client mix. Systeme.io stands out if white-labeling and sub-account management are non-negotiable. Moosend is the only one with an explicit Agency Program in its captured data. GetResponse covers the most ground on captured features. HighLevel’s plan names point at agencies, but the feature detail we captured was too limited to say more — go look at it directly. And HubSpot is the only tool that could realistically serve enterprise-scale client campaigns at its $3,600/month tier, assuming the features hold up under scrutiny.
Run a trial on your top two or three picks, push them against real client workflows, and watch the friction points that reviewers flag — support, billing, and ease of use come up repeatedly across almost every tool here.
