Best Mailjet Alternatives in 2026: 7 Tools Compared

The best Mailjet alternatives are Lumail, Brevo, MailerLite, Elastic Email, SendGrid, Mailgun, and MailerSend, depending on whether you want automations without a Premium plan, extra channels like SMS, a creator website builder, or a developer-only sending API. Mailjet does a lot right: volume-based pricing, a collaborative editor, and marketing plus transactional email in one EU-hosted account. The friction is in the plan gates.

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 Mailjet alternative

• The generous free plan has two ceilings. Free includes 6,000 emails/month, but only 200 a day and 1,000 contacts. Starter at $9/month still caps contacts at 2,000.
• Automations are a Premium feature. Visual workflows start at Premium 15k, from $27/month. Landing pages and A/B testing are Premium too, and downgrading pauses active workflows.
• Overage is steep on smaller plans. Extra emails on the Essential and Premium 15k plans cost $2.58 per 1,000.
• AI access is read-only. Mailjet's MCP server can read contacts, campaigns, and statistics but cannot send email or change settings.

Mailjet alternatives at a glance

Workflow dashboard

1. Lumail: best for workflows and unlimited subscribers on every plan

Lumail keeps what people like about Mailjet (volume-based pricing and marketing plus transactional email in one account) and removes the gates. Graph workflows with triggers, waits, conditions, branches, goals, exit rules, A/B paths, and webhooks are on every plan, including Free. Subscribers are unlimited everywhere. Transactional mail goes through the REST API or smtp.lumail.io:587 with STARTTLS. Where Mailjet's MCP is read-only, Lumail's 89 organization-scoped MCP tools let agents in ChatGPT, Claude, Claude Code, Cursor, and Codex draft campaigns, edit workflows, and manage subscribers, with a CLI, TypeScript SDK, and REST API beside them.

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

Choose it if:

• You want automations without paying for a Premium tier
• Your list is larger than Mailjet's low-plan contact caps
• You want AI agents that can act on your account, not only read it

Watch out for:

• Lumail's free plan has less volume than Mailjet's 6,000 emails
• There is no SMS and no website builder

2. Brevo: best for email plus SMS, WhatsApp, and CRM

Brevo is a multichannel marketing and CRM suite. Like Mailjet, it prices by plan and email volume rather than subscribers alone, and marketing and transactional email are included together. It adds SMS, WhatsApp, contact management, and sales tools on top.

Pricing: Free is 300 emails/day. Starter starts at $9/month and Standard at $18/month.

Choose it if:

• SMS, WhatsApp, or a CRM are required channels
• You want volume-based plans instead of subscriber billing
• A daily free allowance matches how you send

Watch out for:

• Multi-step workflows start on Standard
• The free allowance is daily, so a launch to a large list cannot go out in a single day

3. MailerLite: best for creators who want email and a website

MailerLite is a no-code creator suite: campaigns and visual automations alongside websites, landing pages, forms, digital products, and several email editors. It also offers Claude and ChatGPT integrations. For transactional email, it points you to its sister product, MailerSend.

Pricing: Free is 250 subscribers and 2,500 emails/month. Comfort starts at $12/month and Power at $25/month.

Choose it if:

• You need a built-in website or landing-page builder
• You sell digital products from your email platform
• Your team prefers a no-code editor over API access

Watch out for:

• Pricing follows subscriber tiers, unlike Mailjet's volume plans
• Transactional email needs MailerSend, a separate product

4. Elastic Email: best for low-cost sending on an owned MTA

Elastic Email runs its own in-house MTA and sells three products: Email Marketing (priced by contacts plus a send cap), Email API (priced by volume), and Inbox (priced by seat). It offers landing pages, signup forms, a REST API and SMTP, official libraries for 12 languages, and a hosted MCP server with about 17 actions.

Pricing: The free Email Marketing plan is 1,000 contacts and 3,000 emails/month, capped at 100 a day. Email API Starter is $19/month for 50,000 emails, and Email Marketing Starter is $29/month for 2,500 contacts and 37,500 emails.

Choose it if:

• You want a cheap sending API: 50,000 emails for $19
• You are an agency that needs white-label sending and subaccounts
• You want paid newsletters and Stripe checkouts on the Pro plan

Watch out for:

• The product page places automations on Email Marketing Pro
• Marketing and API are separate products, so combining them means two plans

See the full Lumail vs Elastic Email comparison.

5. SendGrid: best for high-volume delivery at Twilio scale

Twilio SendGrid is a high-volume Email API and SMTP relay with a separately sold Marketing Campaigns product for lists, single sends, signup forms, and drip series. Pro Email API plans include a dedicated IP, subusers, and SSO.

Pricing: New accounts get a 60-day trial with 100 API emails and 100 marketing emails a day. Marketing Campaigns Basic starts at $15/month, and Email API Essentials at $19.95/month. Drip automation needs Marketing Campaigns Advanced, from $60/month.

Choose it if:

• Transactional volume and inbox placement at scale are the priority
• You need dedicated IPs, subusers, and IP pools
• You already buy SMS or voice from Twilio

Watch out for:

• There is no permanent free plan; sending stops after the trial
• Email API and Marketing Campaigns are two subscriptions, where Mailjet uses one

6. Mailgun: best for developer sending with inbound and EU region

Mailgun is Mailjet's sister company under Sinch, aimed at developers rather than marketers. It sends, receives, and tracks application email over REST API and SMTP, with US and EU regions, inbound routes, email validation, dedicated IPs, and an official local MCP server documenting 50+ operations.

Pricing: Free Send includes 100 emails/day. Basic starts at $15/month for 10,000 emails, with extras from $1.80 per 1,000. Foundation is $35/month for 50,000.

Choose it if:

• You only need app email and want to stay with an EU-capable provider
• You need inbound parsing and validation
• Marketers do not need a campaign editor

Watch out for:

• No visual journey builder or newsletter campaign tools
• Optimize and Inspect are separate products with separate bills

See the full Lumail vs Mailgun comparison.

7. MailerSend: best for transactional email with visual template builders

MailerSend is MailerLite's transactional product: REST API, SMTP relay, drag-and-drop and HTML template builders, inbound routing, and US/Canada SMS on higher plans. Its hosted MCP server names 127 tools for sending, domains, templates, and suppressions. Paired with MailerLite, it covers what Mailjet does in one account.

Pricing: Free is 500 emails/month after approval, with a credit card required but not charged. Hobby is $7/month for 5,000 emails, then $1.50 per 1,000. Starter starts at $35/month for 50,000.

Choose it if:

• You only need Mailjet's transactional side
• Non-developers need to edit transactional templates
• You want a hosted MCP for transactional operations

Watch out for:

• Newsletters and marketing campaigns need MailerLite
• No visual journey builder

How to choose a Mailjet alternative

Worked example: 10,000 contacts, two newsletters a month, and a welcome workflow. That is 20,000 emails a month plus one automation.

• Lumail: Premium at $20/month covers 40,000 emails, and workflows are included.
• Mailjet without automations: Essential 15k at $17 + 5,000 extra at $2.58 per 1,000 = $29.90.
• Mailjet with the welcome workflow: Premium 15k at $27 + 5,000 at $2.58 per 1,000 = $39.90.
• Brevo, MailerLite, Elastic Email, and SendGrid: check each pricing page for the tier 10,000 contacts or 20,000 emails lands in. Brevo needs Standard and SendGrid needs Advanced for multi-step automation.

How to migrate from Mailjet

1. Export contact lists with unsubscribes and bounces. Keep suppressed contacts marked so they never receive mail from the new tool.
2. Authenticate your domain. Point SPF, DKIM, and DMARC at the new provider and leave Mailjet running until it verifies.
3. Move transactional sending. Swap in-v3.mailjet.com or the Send API for the new SMTP relay or API (Lumail's is in the SMTP guide) and test every template.
4. Rebuild one automation. Recreate your welcome series as a workflow and run a test contact through it before you cancel Premium, since Mailjet pauses workflows on downgrade.
5. Send one campaign to a segment, then move the rest. Check rendering, links, and unsubscribe handling on a small group before switching the full list.
