About the technology
Transactional email
Mailjet is a cloud email service for sending transactional and marketing messages. Companies use it for account activation, password resets, order updates, invoices, newsletters and product announcements. Its REST API, SMTP relay and template editor support both application-triggered messages and planned campaigns.
API and SMTP
Mailjet integrations connect websites, applications and customer platforms to reliable email delivery. Specialists work with the Mailjet API, SMTP credentials, event callbacks and contact-management endpoints. They also configure authentication records such as SPF, DKIM and DMARC, manage templates, and separate transactional traffic from marketing campaigns.
Campaign ecosystem
The service combines message delivery with tools for contacts, segmentation, automation and reporting. A strong Mailjet professional can work across the surrounding stack, including:
- MJML email templates and responsive HTML
- Mailjet Send API and SMTP relay integrations
- Webhooks for delivery, bounce and spam events
- Contact lists, segments and subscription preferences
- Consent-aware campaign workflows and analytics
When expertise helps
Companies often bring in freelance specialists when a new application needs dependable email, an existing integration has delivery problems, or campaign operations have become difficult to maintain. Expertise is also useful during a migration from another provider, a rework of responsive templates, or a consolidation of several sending domains. Teams in Germany may choose remote collaboration or on-site workshops depending on security, product and marketing needs.
Practical deliverables
Typical work starts with a review of requirements, sending domains and existing message flows. Deliverables can include a Mailjet integration, reusable MJML templates, event-processing logic, contact synchronisation, campaign automations and documentation for internal teams. Professionals should test rendering, retries, unsubscribe handling and failure paths rather than treating successful API calls as the complete solution.
Quality signals
The strongest specialists understand both application logic and email operations. They can explain how Mailjet by Sinch compares with providers such as SendGrid, Amazon SES or Brevo for the project’s delivery, template and workflow needs. Look for clear separation of transactional and promotional messages, careful handling of personal data, useful monitoring, maintainable templates and tests across common mail clients. They should also communicate trade-offs clearly in English or German when working with teams in Germany.
Frequently asked questions
Need clarity? These are the questions we hear most often about Mailjet.
Mailjet is used to send transactional emails and marketing campaigns from applications and business systems. Common examples include welcome messages, password resets, purchase confirmations, newsletters and automated customer journeys.
Mailjet is often considered alongside SendGrid, Amazon SES and Brevo for email delivery and campaign management. The right choice depends on the required API, template workflow, contact features, reporting, integration effort and level of operational control.
A strong Mailjet specialist may also work with REST APIs, SMTP, webhooks, MJML, responsive HTML email and authentication records such as SPF, DKIM and DMARC. Experience with customer data, consent management, CRM or ecommerce integrations is valuable for broader communication workflows.
The right level of Mailjet experience depends on the scope. A simple SMTP setup may need focused integration knowledge, while a multi-system implementation requires expertise in API design, event handling, deliverability, templates, segmentation and operational monitoring.
Yes, Mailjet work is usually suitable for remote collaboration because requirements, credentials, templates and test results can be managed online. On-site sessions may still help when teams need workshops about data flows, consent processes or campaign ownership, and German or English communication can be agreed in advance.
Ask a Mailjet freelancer to explain the proposed sending architecture, authentication setup, bounce handling and separation of message types. Review examples of maintainable templates, documented integrations, monitoring and tests for unsubscribes, failures and different email clients.
Mailjet supports both application-triggered transactional messages and planned marketing campaigns. A specialist should keep these flows logically separated, use appropriate templates and preferences, and ensure that contact updates and unsubscribe events are handled consistently.
A Mailjet expert can investigate failed API calls, SMTP issues, bounce events, incorrect webhook processing and poor email rendering. They can also improve domain authentication, rebuild MJML templates, connect customer systems and document campaign workflows for the team.
