Mailjet review

Mailjet combines marketing campaigns and transactional email in one service. Marketers can design and send campaigns, segment audiences, set up action-triggered workflows, run A/B tests, and track engagement and deliverability. Developers can send through a REST API or SMTP relay, with SDKs and webhooks also listed among its tools.

The editor includes drag-and-drop design, reusable templates, AI assistance, and real-time co-editing. Mailjet also says users can describe audience filters in plain language, then review and adjust the resulting logic. That puts campaign creation and sending infrastructure under one roof, rather than requiring separate marketing and transactional-email products.

Mailjet’s plans are priced by monthly email volume, with contact limits on some tiers. The free plan allows 6,000 emails per month but caps sending at 200 per day. So the headline monthly allowance is not the same as what you can send on a busy day.

Mailjet’s main appeal is breadth: the listed features cover campaign design, automation, segmentation, testing, analytics, and API-based sending. Teams that need both newsletters and transactional messages can manage them through the same service, using the API, SMTP relay, SDKs, or webhooks. The editor’s co-editing and reusable templates may also suit teams sharing campaign work.

The entry pricing is low, and there is a free plan. According to the pricing details checked on November 7, 2026, Free includes 6,000 emails per month, 1,000 contacts, and API, SMTP relay, and webhook access. Starter costs $9 monthly or $8.10 per month with annual billing; it includes 8,000 emails, 2,000 contacts, and no daily sending limit. Essential is $19 monthly or $17.10 annually, with 15,000 emails and unlimited contacts.

Essential also lists 500 email validations and 500 previews per month. Premium costs $29 monthly or $26.10 annually and includes 15,000 emails, automation-oriented positioning, and 2,000 email previews. Annual billing is advertised at 10% off.

The sending and contact caps need a close read. Free allows 6,000 emails a month, but no more than 200 a day; Starter removes the daily limit but is capped at 8,000 monthly emails and 2,000 contacts. Essential raises contacts to unlimited, but still lists 15,000 emails per month. Premium also lists 15,000 emails, so paying more does not automatically mean a higher stated sending allowance. Mailjet says excess emails are billed, but the published pricing information does not publish the rate. Custom pricing is also not published.

Some operational details are unclear from the pricing information: Premium’s dedicated IP is listed for 100,000-plus plans, upon request, and the cost of additional IPs is not published.

Reddit reports are mixed, not a reliable measure of overall service. One commenter described past delivery-log and support delays; another reported an account block after signup. A separate commenter said the editor and automation designer felt less user-friendly than GetResponse, while another disagreed about usability. Treat these as individual experiences, but check support expectations and account approval before moving a critical sending program.

Mailjet starts at $9 per month for Starter, or $8.10 per month with annual billing. The Free plan includes 6,000 emails per month, but caps sending at 200 per day and 1,000 contacts. Starter removes the daily sending limit and raises the contact cap to 2,000, with 8,000 emails per month.

Essential costs $19 monthly ($17.10 annually) and raises the allowance to 15,000 emails, with unlimited contacts. Premium is $29 monthly ($26.10 annually) for the same 15,000-email allowance, plus 2,000 email previews per month. So the jump from Essential buys added features, not more monthly sends.

Annual billing is advertised at 10% off. Emails beyond a plan’s sending limit are billed, but the published pricing details don’t publish the overage rate. The price for additional dedicated IPs is also unpublished. Premium lists one dedicated IP, with availability for 100,000-plus plans upon request. Check the cap and overage terms before moving a larger list.

Mailjet combines marketing campaigns with transactional sending through an API and SMTP relay, so a switch may involve more than moving campaign templates. Inventory your sending integrations, webhooks, automations, audience filters and transactional email before planning the cutover. The published material doesn’t describe Mailjet’s import tools, export formats or migration service, so confirm how contacts, templates and reporting data can be moved before you commit.

The feature list doesn’t establish that data is difficult to leave, either; portability and lock-in details are simply not published here. Ask what you can export and whether your API or SMTP setup needs changes if you move providers. The published sources include no Reddit posts or comments, so we can’t reliably say what users report as their reasons for leaving Mailjet. Treat support quality as something to verify directly, especially since the review verdict flags support reports as a concern—not as a confirmed pattern.
