HeyForm vs Mailjet
A side-by-side editorial comparison of HeyForm and Mailjet — release velocity, themes, recent moves, and the top alternatives to consider.
HeyForm vs Mailjet: at a glance
What is HeyForm?
HeyForm's v3 has been in release candidates for months, now moving mostly on community fixes.
HeyForm has been on v3.0.0 release candidates since at least March 2026, and the recent cuts are small: Italian and Brazilian Portuguese localization, an IPv6 bypass fix in the outbound SSRF guard, and plain-text rendering of group page titles. Most recent changes come from first-time contributors.
What is Mailjet?
Mailjet is publishing deliverability compliance guidance, and little else.
A low-cadence blog — ten posts spanning eight months — weighted toward authentication and regulatory change rather than product. The substantive entries are two treatments of the CNIL and Garante tracking-pixel guidance in France and Italy, and a DMARC post that states a real product default: Mailjet is DKIM-first. The rest is competitive migration content, a platform comparison still labelled 2025, and research published under the sibling Mailgun brand.
HeyForm vs Mailjet: editorial side-by-side
HeyForm
0.0MARKETING
HeyForm's v3 has been in release candidates for months, now moving mostly on community fixes.
◆ Current state
HeyForm has been on v3.0.0 release candidates since at least March 2026, and the recent cuts are small: Italian and Brazilian Portuguese localization, an IPv6 bypass fix in the outbound SSRF guard, and plain-text rendering of group page titles. Most recent changes come from first-time contributors.
◆ Where it's heading
The v3 line is in a long stabilization phase with localization and security patches rather than new form features. Releases have slowed to roughly one every three to six weeks, and nothing has shipped since mid-July.
◆ Prediction
The entries do not show what is blocking a v3.0.0 final; the next release is more likely another RC with community fixes than a stable cut.
Mailjet
2.5MARKETING
Mailjet is publishing deliverability compliance guidance, and little else.
◆ Current state
A low-cadence blog — ten posts spanning eight months — weighted toward authentication and regulatory change rather than product. The substantive entries are two treatments of the CNIL and Garante tracking-pixel guidance in France and Italy, and a DMARC post that states a real product default: Mailjet is DKIM-first. The rest is competitive migration content, a platform comparison still labelled 2025, and research published under the sibling Mailgun brand.
◆ Where it's heading
The positioning is compliance-and-deliverability first, which is the pitch of an infrastructure sender rather than a campaign tool — the transactional-plus-marketing post argues exactly that, against teams running two platforms. The Mailchimp migration guide and the comparison roundup point at where Mailjet expects to win customers: cost and consolidation, not features. Nothing in the window describes a shipped capability.
◆ Prediction
More regulatory response content is the safest read, since two of the last ten posts already cover the same EU pixel guidance; on product direction this source is silent and a release feed would be needed.
