Quick answer: The best Mailjet alternatives in 2026 are Bluey Email (automation + CRM, unlimited contacts from $30/mo), Brevo (email + SMS + CRM), Sender (best free plan), MailerLite (design on a budget), Mailchimp (biggest ecosystem), Kit (creators), and Omnisend (ecommerce). People look past Mailjet because, in EmailTooltester’s words, "the automation builder still feels a bit behind competitors, and support can be hit or miss unless you’re on a higher plan" (EmailTooltester). Full disclosure: Bluey is my own product; I rank it first for a specific, verifiable reason and say plainly where each rival wins.
Mailjet is a solid, affordable sender — especially for transactional email and cheap entry ($9/mo for 8,000 emails, plus a 6,000-email free plan) (Mailjet pricing). But if you want deeper automation, a CRM, SMS, or a more generous free tier, here’s where to look.
Why look for a Mailjet alternative?
Automation is gated and light. Mailjet’s automations and landing pages only unlock on the Premium plan ($27/mo), and EmailTooltester’s Inka Wibowo still rates the builder as "a bit behind competitors" (EmailTooltester).
Support can be inconsistent. The same review notes support "can be hit or miss unless you’re on a higher plan" (EmailTooltester).
No built-in CRM or SMS. Mailjet is email-only; if you want texting or contact management in the same tool, you’ll be stitching apps together.
The 7 best Mailjet alternatives
1. Bluey Email — best for automation and a flat bill
Who it’s for: senders who want serious automation without paying to unlock it, plus a CRM. Bluey bills by emails sent. Free covers 500 contacts / 500 sends; Spark starts at $7/mo (~$14 at 10,000 sends); Grow is $30/mo with unlimited contacts (~50,000 sends); Business is $300/mo with a built-in CRM, landing pages, transactional email, and pre-built ecommerce flows. The substantiated reason it leads: Bluey includes the visual automation builder and segmentation on every paid tier, while Mailjet gates automation behind its $27/mo Premium plan — and offers no CRM at all. See the Bluey vs Mailjet comparison.
Where Mailjet wins instead: a cheaper $9 entry plan, a bigger free tier (6,000 emails), a mature transactional API, and up to 20 sub-accounts for agencies.
2. Brevo (formerly Sendinblue) — best for email + SMS + CRM
Who it’s for: teams that want email, SMS, and a CRM in one tool with volume-based pricing. Brevo covers the channels Mailjet leaves out.
Where Mailjet wins: simpler transactional setup and sub-accounts for multi-brand agencies.
3. Sender — best free plan
Who it’s for: small lists that want the most for free. Sender’s Free Forever plan covers 2,500 subscribers and 15,000 emails/month with automation and SMS-ready paid tiers (Sender pricing) — far more generous than Mailjet’s free plan.
Where Mailjet wins: volume-based pricing with no subscriber cap, plus transactional email and deliverability tooling.
4. MailerLite — best design on a budget
Who it’s for: those who want a richer drag-and-drop editor, landing pages, and websites at a low price.
Where Mailjet wins: cheaper transactional sending and agency sub-accounts.
5. Mailchimp — best ecosystem
Who it’s for: teams that want the most integrations and templates. Mailchimp’s ecosystem dwarfs Mailjet’s.
Where Mailjet wins: dramatically cheaper as you scale, and no aggressive upsells.
6. Kit (formerly ConvertKit) — best for creators
Who it’s for: creators who monetize across products and want a creator-focused automation builder and commerce tools.
Where Mailjet wins: far cheaper for high-volume transactional and campaign sending.
7. Omnisend — best for ecommerce
Who it’s for: Shopify and WooCommerce stores that want pre-built ecommerce automations and email + SMS tuned for revenue.
Where Mailjet wins: general-purpose sending and a developer-friendly API beyond ecommerce.
How to choose a Mailjet alternative
Start from what pushed you to leave. If it’s gated or light automation, pick Bluey or Brevo. If you want email + SMS + CRM, Brevo or Bluey (CRM) plus a texting tool. If you want the most generous free plan, Sender. If it’s design, MailerLite. If you want the biggest ecosystem, Mailchimp. If you’re a creator, Kit. If you run an online store, Omnisend.

Which alternative has the best free plan? Sender — 2,500 subscribers and 15,000 emails per month, free forever (Sender pricing).
Which has the best automation? Bluey and Brevo — both go well beyond Mailjet’s gated builder, and Bluey includes automation on every paid tier.
Is Mailjet good for transactional email? Yes — its Send API and SMTP relay are a genuine strength, so keep it in mind if transactional is your main need (Mailjet pricing).
Which alternative is cheapest at scale? A send-based tool like Bluey (Grow $30/mo, unlimited contacts) stays flat as your list grows.
The verdict
Mailjet is worth keeping if you want cheap, developer-friendly transactional email and agency sub-accounts. But if gated automation, no CRM, or a thin free plan are the friction, start with Bluey Email — send-based pricing, a flat $30/mo, automation and a CRM included — then Brevo for SMS, Sender for a bigger free plan, and MailerLite for design.
