What I like best about Mailjet is its balanced mix of transactional email reliability and marketing campaign tools wrapped with granular contact governance controls, which works really well for my aerospace supply-chain compliance work across Southwest part distributors and Part 145 MRO shops. As an independent compliance consultant, I spend a lot of time coordinating audit notices, supplier document requests and training reminders that have to stay aligned with ITAR and CMMC expectations, and its segmented contact management paired with immutable delivery logs saves me hours each week assembling proof of controlled communications for pre-audit packages.
Most of my clients run lean teams without dedicated marketing staff, so they need one tool for both routine operational alerts and formal outreach to subcontractors, FAA auditors and component vendors. I rely heavily on the contact workspace, automation builder and built-in statistics dashboard. When I set up recurring workflows for them, we separate restricted ITAR-related distribution lists from general training announcements. Mailjet lets me tag contacts by supplier, part family and audit cycle, so we never accidentally send controlled material to an unapproved recipient. Last month I configured this for a small MRO facility that previously sent compliance notices from regular business email. Before Mailjet, their lead tech would forward PDF certificates and audit reminders one by one, keep loose inbox folders, and manually log who received each notice. It was easy to lose delivery confirmation, and auditors repeatedly flagged their lack of traceable communication records.
One unexpected benefit I found is the detail baked into every delivery event log. For aerospace compliance, it is not enough just to send an email; you need verifiable evidence that the right party received and opened a notice within a required window. Mailjet’s stats capture timestamps for sends, deliveries and opens on each recipient, and these records export cleanly into the evidence binders I prepare for CMMC assessments. I can pull these reports without leaning on custom API scripts, which is critical because most of my clients do not have in-house developers. The profile update screen also makes it simple for stakeholders to maintain accurate supplier contact information and mark which distribution lists they belong to, without me needing to edit every entry manually.
I also use its template system to standardize compliance communications. All supplier document requests, training expiration alerts and pre-audit checklists follow the same branded structure, so recipients immediately recognize official notices and are less likely to ignore them. I keep transactional emails such as work order confirmations separate from campaign sends, and Mailjet handles deliverability consistently even when we send batches of ITAR-controlled notifications to multiple vendors at once.
That said, Mailjet is not built for the blockchain document traceability I use in Aeroplicity for part certificates. It only manages communications, not the part trace records themselves. Even so, it fills a major gap. Before Mailjet, clients relied on regular email threads with no centralized audit trail. Now every compliance outreach has a recorded, exportable history. For my consulting practice, this means I spend less time chasing down screenshot proof and more time guiding these distributors and MROs through stronger, repeatable compliance procedures ahead of formal audits.

What I dislike most about Mailjet is its limited granular audit logging, rigid role permissions, and inflexible export controls, which create recurring hurdles when I build controlled communication workflows for aerospace MROs and part distributors that must satisfy ITAR and CMMC requirements. As a supply-chain compliance consultant, my deliverables rely on fully traceable, tamper-evident records of every restricted notice sent to suppliers, and these gaps force my clients to layer manual safeguards that defeat the purpose of moving away from unmanaged inbox threads.
The biggest shortfall is that its activity logs only capture high-level send events, with no fine-grained audit trail for user actions inside the platform. Last month I set up a restricted distribution list for ITAR-controlled supplier notifications. When a client’s operations lead edited contact details or removed a vendor from the list, Mailjet did not log who made the change, the exact timestamp, or the prior value of the record. For aerospace audits, that is a critical gap. CMMC assessors regularly ask for proof that only authorized personnel modified restricted recipient rosters. Without this history, I have to require the team to keep a separate change log in a spreadsheet, adding hours of manual oversight and introducing risk of human error when staff rotate through seasonal maintenance cycles.
Second, the built-in permission roles are broad and cannot be split to separate list editing from bulk export access. I often need to grant MRO coordinators the ability to add new suppliers and trigger compliance reminders, while blocking them from downloading the full restricted contact roster. Mailjet’s predefined roles do not support that split. If someone has campaign and contact access, they can export the entire list. Many of these shops are small and rely on temporary technicians, so owners are reluctant to onboard them fully. They fall back to shared logins, which completely erases individual accountability for sensitive contact data.
Third, the export engine does not preserve full message content alongside delivery metadata in a single audit package. I can pull send timestamps and open events, but the exported CSV does not include the email body sent to each recipient. When auditors request a copy of the exact notice delivered to a supplier, I have to manually capture screenshots or save individual message copies one by one. This slows pre-audit evidence collection significantly, especially during busy FAA inspection windows when turnaround time is tight. The webhook payloads also lack support for passing internal compliance tags over to Aeroplicity, where we store the component certificates, so we still have to cross-reference identifiers manually between the two systems.
My recommendations would be to add immutable, timestamped change logs for contact and list edits, introduce custom permission toggles that separate edit rights from bulk export privileges, and build an audit export bundle that bundles recipient metadata plus the final delivered message text. Mailjet works well for basic compliance outreach, but it was not engineered for the strict non-repudiation rules of defense aerospace supply chains. With those improvements, I would spend far less time patching gaps in its traceability and more time helping these MROs build repeatable, audit-ready communication controls.
