Best Campaign Monitor Alternatives in 2026: 6 Tools Compared

The best Campaign Monitor alternatives are Lumail, Mailchimp, Brevo, Constant Contact, MailerLite and Zoho Campaigns, depending on whether you want a real free plan, lower cost at 10,000+ contacts, SMS and CRM, local small-business support, or cheap agency accounts. Campaign Monitor by Marigold is a polished, design-led tool with a good builder and transactional email on monthly plans. The reasons to leave are usually price and plan structure, not quality.

We make Lumail, so it is listed first; every other entry is judged on the same criteria with facts from each vendor's pricing page as of August 2026.

Why people look for a Campaign Monitor alternative

• There is no free plan. Campaign Monitor's help center states it is not a free product. The 30-day trial allows 500 contacts and 500 emails, at most 100 a day.
• Price jumps with each contact tier. Lite starts at $13/month for up to 500 contacts, but 5,001 to 10,000 contacts costs $117/month on Lite and $182/month on Essentials.
• Lite caps sends. Lite limits monthly sends to five times your contact tier, and automated and transactional emails count toward that cap.
• AI stays inside the builder. AI Writer and Email Booster help draft and optimize, but there is no official MCP server or CLI for agents.

Campaign Monitor alternatives at a glance

Workflow dashboard

1. Lumail: best for large lists and agent-run email

Lumail bills by emails sent and stores unlimited subscribers, so a growing list does not push you into the next tier. Campaigns, graph workflows and transactional email share one organization, like Campaign Monitor's monthly plans, but there is no send cap tied to list size and no plan gate on workflows. The difference that matters most for modern teams: the account is operable through 89 organization-scoped MCP tools in ChatGPT, Claude, Claude Code, Cursor and Codex, plus a CLI, TypeScript SDK and REST API.

Pricing: Free for 3,000 emails/month, no card. Premium is $20/month with 40,000 emails included, then $0.60 per 1,000. Business is $200/month with 400,000 emails, then $0.40 per 1,000.

Choose it if:

• your contact count keeps pushing you up Campaign Monitor tiers;
• you want transactional email via API or SMTP on every plan, including Free;
• AI agents or scripts should create campaigns, manage segments and read results.

Watch out for:

• no agency white-label or client billing, and no website builder; Lumail offers capture pages for list growth only.

2. Mailchimp: best established all-in-one suite

Mailchimp is the familiar default for general marketing teams: campaigns, audiences, templates, landing pages, forms, websites and a very large integration ecosystem.

Pricing: Free for 250 contacts and 500 sends a month. Paid pricing varies by plan, contact tier and monthly send allowance.

Choose it if:

• you want a free plan to start, which Campaign Monitor lacks;
• your team relies on Mailchimp's integrations;
• you want website and landing-page tools in one suite.

Watch out for:

• the free plan is small, and paid pricing still follows the stored contact count;
• transactional email is a separate Mailchimp Transactional add-on.

3. Brevo: best for email plus SMS and CRM

Brevo pairs marketing and transactional email with SMS, WhatsApp, a sales CRM and multichannel campaigns. It prices by email volume rather than only by contacts, which is closer to how you actually send.

Pricing: Free for 300 emails per day. Starter from $9/month, Standard from $18/month.

Choose it if:

• SMS or WhatsApp need to sit next to email;
• you want marketing and transactional email in one account.

Watch out for:

• multi-step workflows start on Standard;
• the free plan's 300-a-day cap rules out a single send to a larger list.

4. Constant Contact: best for local businesses and nonprofits

Constant Contact bundles email with social posting, SMS, event ticketing, landing pages and ads, with phone and chat support and 1:1 onboarding on paid plans.

Pricing: No permanent free plan; a 30-day trial. Lite from $12/month, Standard from $35/month and Premium from $80/month, each for 0–500 contacts.

Choose it if:

• you want live phone support and guided onboarding;
• you run events, post to social or buy ads from the same dashboard;
• you are a nonprofit or multi-location brand.

Watch out for:

• Lite includes one automation path and Standard three;
• it bills the highest contact count in the period, and extra campaign sends cost $0.002 each.

5. MailerLite: best budget option with a website builder

MailerLite combines campaigns and visual automations with websites, landing pages, forms and digital products, and several email editors. It suits design-conscious teams that want a lower bill.

Pricing: Free for 250 subscribers and 2,500 emails/month. Comfort from $12/month, Power from $25/month.

Choose it if:

• you want a website and landing pages without paying extra for a builder;
• you like MailerLite's templates and integrations.

Watch out for:

• transactional email lives in MailerSend, a separate product;
• automation counts are limited by plan.

6. Zoho Campaigns: best for Zoho users and budget agencies

Zoho Campaigns is contact-priced email with unlimited sends on paid plans, native sync with Zoho CRM and other Zoho apps, and an Agency Edition for managing client accounts.

Pricing: Forever Free with 2,000 contacts and 6,000 emails/month. Standard starts at $4/month for 500 contacts; at 10,000 contacts Standard is $49/month and Professional $81/month.

Choose it if:

• your business already runs on Zoho;
• you are an agency and want Agency Edition (yearly, minimum 10,000 contacts, up to 10 clients).

Watch out for:

• no workflows on the free plan;
• transactional email is a separate product, ZeptoMail.

How to choose a Campaign Monitor alternative

Most Campaign Monitor alternatives build good-looking emails, so the decision comes down to billing, plan limits and who operates the account.

• Pricing basis vs list shape. If you store many contacts and email segments, send-based pricing (Lumail) or volume-based plans (Brevo) usually beat contact tiers.
• Free plan vs trial. Mailchimp, Brevo, MailerLite, Zoho Campaigns and Lumail have lasting free plans. Constant Contact, like Campaign Monitor, offers only a trial.
• Transactional email. Campaign Monitor includes it on monthly plans. Of the alternatives, Lumail and Brevo keep it in the same account; Mailchimp, MailerLite and Zoho sell it separately.
• Agency needs. If white-label client billing is essential, Campaign Monitor and Zoho's Agency Edition are built for it. Lumail is not.
• AI and developer access. In-app AI drafts copy. MCP, CLI and SDK access lets an agent run the account.

A worked example: 10,000 contacts, two newsletters a month

Two sends to 10,000 contacts is 20,000 emails a month. Monthly list prices:

A list under 500 contacts flips the picture: Campaign Monitor Lite at $13 or Constant Contact Lite at $12 can then cost less than Lumail Premium, and Lumail Free covers you only while you stay under 3,000 emails.

How to migrate from Campaign Monitor

1. Export subscribers and suppressions. Export each list with custom fields, plus unsubscribes and bounces. Merge duplicates, since the same person on two lists counts twice on Campaign Monitor.
2. Authenticate your domain. Set up SPF and DKIM on the new platform. Keep Campaign Monitor running until the domain verifies.
3. Rebuild one journey. Recreate your welcome journey as a workflow and test it with internal addresses.
4. Send a test campaign to one segment. Check rendering, links and bounce rates on a small, engaged segment.
5. Move the rest and cut over transactional. Import everything else, then point transactional traffic from smtp.api.createsend.com to the new provider before cancelling.
