Sender is an email marketing platform that combines affordability with surprisingly strong features. It's built for small businesses and startups who need professional email marketing without the premium price tag. The free plan alone covers most businesses' basic needs.
This is the email marketing tool I'd recommend to any startup or small business looking to get serious about email without breaking the bank.

Features
What can Sender do?
Going through Sender's dashboard, the drag-and-drop email builder excels as intuitive. You can start with one of their 1600+ templates or build from scratch, and the editor handles responsive design automatically. The HTML editor gives you full control when needed, while the visual builder keeps things simple for non-technical users.
The automation capabilities impressed me most. Setting up welcome sequences, abandoned cart emails, and behavioral triggers is straightforward, with visual workflow builders that make complex automation accessible. The premade sequences cover common scenarios like lead nurturing and customer onboarding, saving significant setup time.
Lead capture tools integrate smoothly with the main platform. Creating signup forms and popups takes minutes, and the landing page builder, while basic, covers essential needs without requiring external tools. The segmentation features let you target based on behavior, demographics, and engagement levels, though they're not as advanced as specialized platforms.
Deliverability features deserve special mention. Sender claims 99% inbox delivery rates through dedicated infrastructure, monitored IP reputation, and built-in compliance tools. The transactional email capabilities handle order confirmations, password resets, and other automated messages through the same platform, eliminating the need for separate services.

UX & Support
Is Sender easy to use?
Setting up a first campaign in Sender takes under 10 minutes, from account creation to sending. The onboarding process guides you through essential steps without overwhelming new users. The dashboard layout feels familiar to anyone who's used modern web applications, with clear navigation and logical feature grouping.
The template library deserves praise for both quantity and quality. With 1600+ options covering industries from e-commerce to nonprofits, finding a suitable starting point is rarely an issue. Customization options are extensive enough for most needs while remaining accessible to non-designers.
Customer support lives up to their 24/7 availability promise. By user reports, chat responses come within the claimed 10-second average, with knowledgeable representatives who understand both technical and strategic questions. The knowledge base covers common scenarios thoroughly, and video tutorials help visual learners get up to speed quickly.
Pricing
How much does Sender cost?
Sender starts at From $7/mo. That's 53% below median for Email Marketing. A free plan is available.
Sender Pricing Analysis
vs. 36 email marketing toolsBelow average for email marketing tools
Cheaper than 97% of email marketing tools on That Marketing Buddy's database. Sender also offers a free plan.
Sender's pricing structure centers around a generous free plan that includes 15,000 emails monthly for up to 2,500 subscribers with no daily limits. The free plan includes marketing automation, 24/7 support, and access to all templates, making it more comprehensive than most competitors' free offerings.
Paid plans start at $7 monthly based on available information, scaling with subscriber count and email volume. The pricing remains competitive compared to alternatives like Mailchimp or Constant Contact, particularly when factoring in included features like SMS marketing and automation capabilities.
Value assessment strongly favors Sender, especially for smaller businesses. Getting automation features that typically cost $50+ monthly on other platforms included in the free tier represents significant savings. Even paid plans offer better feature-to-price ratios than most mainstream alternatives.

What does the Sender free plan include?
Sender offers a Free Forever plan with basic email marketing features and sending limits.
Which Sender plan should you pick?
The free-forever plan gives you a genuine starting point with enough contacts and email sends to run your first campaigns at no cost. Sender's free tier includes automation features that many competitors reserve for paid plans, so you can test triggered sequences without spending money. For beginners learning email marketing fundamentals, this provides hands-on experience without any financial risk. Upgrade to Standard when you need higher contact limits, more sends, or want to remove Sender branding from emails.
Standard at $7/month is one of the cheapest paid email plans available, providing increased sending limits and additional features beyond the free tier. The low price point makes it accessible for small businesses that want professional email marketing without a significant monthly expense. For businesses that have outgrown the free plan but do not need advanced automation, Standard covers the essentials reliably. Move to Professional when you need advanced automation capabilities or higher sending limits for growing campaigns.
Professional adds advanced automation and higher sending limits for businesses that run complex email campaigns. The expanded automation capabilities support multi-step conditional sequences and behavioral triggers that drive revenue. For companies where email is a primary sales and communication channel, the advanced features help optimize campaign performance over time. If your email strategy is relatively straightforward, Standard provides enough capability at a lower cost.
Does Sender have hidden costs?
6 outside the plan price- 1
SMS credits charged separately on Standard plan
The Standard plan includes SMS messaging, but if you exceed your included SMS allowance or need additional SMS credits, you must purchase them separately. SMS pricing varies by destination country and is charged per message sent.
- 2
Automatic tier upgrade billing if limits exceeded
If you exceed your monthly sending limit and reach another pricing tier, you'll be automatically charged at the higher tier level on or before your next billing date. This happens even if the billing term ends before the payment is due.
- 3
No refunds policy with strict exceptions
Refunds are only provided if Sender terminates services without cause before the end of a paid year. No refunds are given for account suspensions due to policy violations, unused/partially used plans, wrong plan purchases, immediate cancellations after billing, or forgetting to cancel subscriptions.
- 4
Prepaid email credits expire after 12 months of inactivity
Purchased email credits remain in your account as long as it's active, but if your account shows no activity for 12 months, it may be considered inactive and your email credits may expire.
- 5
VAT not included in displayed prices
VAT is excluded from all displayed prices and varies by country (ranging from 5% to 25%). For example, Germany has 19% VAT while France has 20% VAT, which will be added to your final bill.
- 6
Dedicated IP only available for Professional plan with 20,000+ subscribers
Dedicated IP addresses are available for Professional plan accounts with 20,000 subscribers or above, provided at no additional cost upon request. Lower-tier plans and smaller subscriber counts use shared IP addresses.

Is Sender Worth the Price?
7/10 valueSender delivers functional email and SMS marketing at rock-bottom prices. The $7/month entry point is hard to beat, and the free plan reduces risk. The main limitation is that Enterprise has no public number and fewer advanced features than platforms charging 2-3x more. It is a solid budget option for basic needs. Compare it with Moosend and MailerLite.
Sender's $7/month starting price is among the lowest in the email marketing space. The free plan with basic features gives you a genuine way to test the platform, and the Standard plan adds multichannel automation (email + SMS) at a price where most competitors only offer email. For small businesses watching every dollar, that value matters.
The one gap is Enterprise, which shows no number at all and routes you to a demo. Everything below it is published: Free at $0, Standard at $7/month, Professional at $14/month, each scaling with subscriber count. Compare with Moosend at $9/month or MailerLite at $10/month, both of which publish every tier the same way.
Sender fits small businesses and startups that need basic email and SMS marketing on a tight budget. The free plan and low-cost Standard tier cover the fundamentals. If you are building an email list from scratch and cost is the primary concern, Sender is worth testing alongside its budget-friendly competitors.

Visit SenderMCP Server
Does Sender have an MCP server?
Sender ships a first-party MCP server at mcp.sender.net/mcp, so Claude, ChatGPT or Cursor can read your subscribers, segments and automations and build drafts in your account without any glue code.
https://mcp.sender.net/mcpSender runs an official MCP server at https://mcp.sender.net/mcp over HTTP. Auth is OAuth: you add the URL as a connector, log in to Sender in a browser window, approve the permissions, and there is no API key to paste anywhere. The token is scoped to the role of the user who authorized it, so a limited role produces a limited view, and disconnecting is a one-click removal on the client side.
The documented surface runs to 40 tools across six groups: account and domain discovery, subscribers and groups, segments, email campaigns, workflows, and the image library. Workflows get the deepest coverage at 14 tools, including a validate_workflow dry run that returns every blocking problem at once instead of one per attempt. Segment reads come back with a plain-English readback of the conditions, which is how an assistant catches a "30-day most engaged" segment still filtering on a fixed date from two years ago.
The guardrails are the interesting part. Campaigns are never sent through this connection, because no tool exists that sends one. Workflows are created inactive and go live only through a separate activation step that runs the same pre-flight checklist as the dashboard. Destructive actions need an explicit acknowledgment flag, drag-and-drop designs stay read-only unless you allow an overwrite, and workflow creation is capped at 50 per account per day.
How to connect Sender to Claude, ChatGPT or Cursor
Connection is a URL and an OAuth login. Add https://mcp.sender.net/mcp as a custom connector, approve access in the browser window Sender opens, and the token is scoped to your account. There is no API key to copy, rotate, or leak into a config file. On Claude Team and Enterprise plans a Claude organization Owner has to add the connector at org level before members can authorize their own Sender accounts.
Sender does not sell the server as an add-on. It follows your existing plan features and your user role: every tool checks a permission, and if your role cannot edit campaigns in the dashboard it gets a permission error here and explains why. Anything that will eventually send needs a verified sending domain, and the server reports SPF, DKIM and DMARC status per domain, so you find out before a draft blocks rather than after.
Running several brands? Add one connector per account with distinct names, authorize each with its own login, and enable only the one you intend to work in for a given conversation.
| Client | Support | Notes |
|---|---|---|
| Claude (desktop, web, mobile) | Native | Customize then Connectors, add custom connector, OAuth sign-in. Works on web, desktop and mobile. Team and Enterprise plans need an org Owner to add it first. |
| ChatGPT | Native | Requires Developer mode under Settings then Plugins, and you have to select the Sender app in the composer each time. |
| Cursor | Native | Cursor Settings then MCP then New MCP Server, or a {"mcpServers":{"sender":{"url":"https://mcp.sender.net/mcp"}}} entry, then the OAuth prompt. |
What you can do with the Sender MCP server
Sender documents three clients. Claude works on web, desktop and mobile through Customize then Connectors. ChatGPT needs Developer mode switched on under Settings then Plugins before a custom MCP server can be added at all. Cursor takes a two-line mcpServers entry pointing at the same URL. All three finish on the same OAuth flow.
The prompts that earn their keep are audits rather than drafting. Ask which automations overlap and you get the merged picture across every active workflow, which the dashboard makes genuinely hard to see: two flows sharing a trigger event means everyone who enters one enters the other, and stacked delays can land five emails in nine days. Pull the per-workflow report next and the overlap gets priced in unsubscribes.
Content checks are the other one. The assistant reads campaign and workflow email bodies and flags legacy {$firstname} tokens (Sender runs on Liquid, so it is {{ firstname }}, and the old syntax reaches subscribers as literal text), missing preheaders, and social icons carrying the wrong alt text.
MCP verdict
An official OAuth server with 40 documented tools covering reads and writes across subscribers, segments, campaigns and workflows, wrapped in draft-only guardrails that stop an assistant mailing your list. It earns an 8 out of 10: unusually complete for a budget email tool, with no separate fee or plan gate on the connection itself. What holds it back is the layer underneath, where there is still no public OpenAPI spec and no official server-side SDKs.
Comparing tools on agent support? See every marketing tool with an MCP server.
Public API
Does Sender have an API?
Sender runs a versioned REST API at api.sender.net/v2 covering subscribers, campaigns, workflows and webhooks, with tokens you generate yourself in the dashboard.
The API lives at https://api.sender.net/v2 and you authenticate with an access token created in the dashboard under Settings then API access tokens. No OAuth app registration, no partner approval, just a token you generate and send with the request.
Resource coverage is wider than a budget email tool usually bothers with: subscribers (including group and phone management), groups, segments, custom fields, statistics broken out by clicks, opens, bounces and complaints, campaigns with create, send, schedule, copy and delete, transactional campaigns with and without templates, workflows with start and performance calls, custom events, and account webhooks.
Webhooks are the piece that matters for anything event-driven. They are documented with full create, read, update, delete and list endpoints plus a published example payload, so you can react to subscriber and campaign events instead of polling for them.
The gaps are on the developer-experience side. There is no OpenAPI spec published on the docs, so you hand-roll clients rather than generating them, and the only SDK is the browser tracking snippet, which is not a server-side client. No rate limit is stated on the documentation either, which is the kind of number you want before you point a batch job at it.
Sender API pricing and rate limits
The API costs nothing on top of your plan. Tokens are generated in Settings then API access tokens, and the calls you can make follow the features your plan already includes, so a Free Forever account can drive the API within its own 2,500 subscriber and 15,000 email a month ceiling.
No rate limit is published on the documentation, which is worth knowing before you plan a bulk import or a nightly sync. Budget for backoff and retry logic rather than assuming a ceiling, and test a batch at small volume first. If you want an agent working the account rather than a scheduled job, the MCP server is the lower-effort path: it carries the same permissions with none of the client code.
API verdict
A properly versioned REST API with real coverage: subscribers, segments, campaigns, workflows, statistics and webhooks, authenticated with a self-serve token. It earns a 6 out of 10. Everything an integration needs is reachable, but no published OpenAPI spec, no server-side SDKs and no documented rate limit mean you write more client code and do more guessing about limits than the best-in-class email APIs ask of you.

Aggregated from 2 platforms
Sender holds a 4.7/5 average rating across 443 reviews on Capterra, G2.
"I have tried other email marketing platforms, but I am staying with Sender! I have tried email newsletters and campaign platforms that mostly give you nothing but lies in their free plans, but Sender practically gives you a premium experience even in the free plan."
Capterra"Sender.net is very affordable and easy to use, the ability to customize email templates and analytics helps improve campaigns constantly and effectively. There are no restrictions on features such as drag-and-drop feature or pre-made templates."
Capterra"I found Sender a more practical, functional tool with better benefits than Mailchimp."
Capterra"It's everything Mailchimp was not: generous, easily accessible customer service, generous features, even automation on the free plan, easy to use drag-and-drop builder, much better than Mailchimp's."
Capterra"Great support made my onboarding a breeze! Sender perfectly fits my needs and allows me to expand as needed."

What that means for your stack
What AI Can't Replace
Sender owns your email deliverability infrastructure and list hygiene in ways no AI can replicate. The tool's real-time bounce handling, SMTP infrastructure, and list validation catch issues before they tank your sender reputation. AI can write the email, but it cannot manage the technical pipes that keep you out of spam folders.
Where AI Is Catching Up
AI content generation is eating into Sender's template and copy features. Claude or ChatGPT can now write email sequences faster than Sender's editor can format them. The risk is real if you're paying for Sender mainly for creative work rather than deliverability and list management.

Downsides
What's wrong with Sender
Limited Language Support
Interface only available in English, Lithuanian, Polish, and Spanish, restricting global teams.
Basic SMS Features
SMS marketing capabilities are functional but lack advanced features found in dedicated SMS platforms.
Simple Analytics
Reporting covers essentials but lacks advanced segmentation and custom dashboard options.
Template Customization
While extensive, template modifications are less flexible than platforms with advanced design tools.
Integration Ecosystem
Fewer third-party integrations compared to established platforms like Mailchimp or HubSpot.
Advanced Automation
Complex behavioral triggers and multi-step workflows are more limited than specialized automation platforms.
Are these dealbreakers?
For a free tool (or even at the paid tier prices), these are reasonable trade-offs. You'll notice the gaps mainly if you're comparing Sender to platforms that cost 3-5x more.
