• Deliverability & email Sending. Sender places a strong emphasis on email deliverability, offering features like dedicated IP addresses, advanced email authentication protocols, and real-time deliverability monitoring. While Mailjet provides reliable delivery, Sender goes the extra mile to ensure your emails reach the inbox;
• Automation & workflows. Both platforms offer marketing automation, but Sender provides a more robust and sophisticated system. It allows for complex branching logic, advanced segmentation options, and a wider range of triggers and actions to create highly personalized email sequences;

ActiveCampaign vs. Mailjet

ActiveCampaign and Mailjet are both reputable email marketing platforms, but they cater to different needs and levels of marketing sophistication.

Mailjet, on the other hand, focuses primarily on providing a user-friendly and collaborative email marketing experience.

• Marketing automation. ActiveCampaign shines in its robust marketing automation capabilities, offering a wide array of triggers, actions, and conditions to create complex and highly personalized email sequences. While Mailjet offers automation features, they are more streamlined and geared towards simpler workflows;
• CRM & sales features. ActiveCampaign goes beyond email marketing by providing built-in CRM and sales automation features, allowing businesses to manage contacts, track deals, and automate sales processes within the same platform. Mailjet focuses solely on email marketing and does not offer these additional functionalities;
• Pricing. ActiveCampaign’s pricing is typically higher than Mailjet’s, reflecting its more advanced features and comprehensive marketing suite. ActiveCampaign’s pricing is based on contact list size and feature access, while Mailjet offers plans based on email volume and contact tiers.

We moved to ActiveCampaign from two separate systems — one a CRM and one an email marketing provider. Having the capabilities for both of these in one solution has been amazing. I love how easy it is to use ActiveCampaign for creating and sending our marketing emails.

Mailjet’s pricing is generally more competitive, with a free plan with more features and paid plans that scale based on email volume and contact tiers;

Mailgun vs. Mailjet

Mailgun and Mailjet are both well-established email service providers. However, Mailgun focuses primarily on transactional emails and developer-friendly tools, making it ideal for tech-savvy users and businesses with high sending volumes. Mailjet, on the other hand, offers a more balanced approach.

• Target audience. Mailgun caters primarily to developers and businesses with technical expertise, offering a robust API, webhooks, and advanced deliverability features for transactional emails. Mailjet targets a wider audience, including marketers and businesses without extensive technical knowledge, prioritizing ease of use and intuitive design tools;
• Email focus. Mailgun specializes in transactional emails, such as password resets, order confirmations, and account notifications, ensuring high deliverability and fast sending speeds for these critical communications. Mailjet provides a balanced approach, offering robust features for both transactional and marketing emails, making it versatile for various use cases;
• Pricing. Mailgun’s pricing is primarily volume-based, charging based on the number of emails sent, making it suitable for high-volume senders. Mailjet offers flexible plans based on both email volume and contact list size, including a free plan for low-volume senders.

We use Mailgun for a while now and we really like it. Currently we’re using it as a standard for all our transactional mailings on new projects. Also, when we experienced difficulties and reached out to the support, we’ve been amazed about their qualified response.

Postmark vs. Mailjet

Both Postmark and Mailjet are reputable email service providers, but they cater to different needs. Postmark excels in transactional emails, prioritizing speed, reliability, and deliverability for mission-critical communications.

Mailjet, on the other hand, offers a more versatile platform encompassing both marketing and transactional emails, with a focus on user-friendliness and design flexibility.

• Core focus. Postmark specializes solely in transactional emails, while Mailjet offers both transactional and marketing email features.
• Pricing. Postmark operates on a volume-based pricing model, making it ideal for businesses with high sending volumes. Mailjet provides flexible plans, including a free tier for low-volume senders and scalable paid options;
• Ease of use. Mailjet boasts a more intuitive interface and drag-and-drop email editor, making it easier for beginners to design and send emails. Postmark prioritizes developer-friendliness, offering robust APIs and documentation for custom integrations.

It’s a great SMTP provider that is easy to set up as well as great delivery and clean IPs. On top of that, it also has a DMARC reporting tool which I like and recommend to any beginner or non-techy person out there. Support is great and quick to reply to any issues you might have.

Mailjet Alternatives FAQs

How does Mailjet compare to Mailchimp?

Mailjet and Mailchimp are both popular email marketing platforms, but they cater to different needs. Those looking to switch from Mailjet often consider Mailchimp for its more balanced approach between marketing and transactional emails and a more intuitive interface for managing both.

Mailchimp provides a more comprehensive marketing platform with additional features such as landing pages, social media management, and more extensive template options. The best choice depends on your specific marketing requirements and budget. This Mailjet comparison highlights some key differences.

Is Mailjet a reliable email marketing service provider?

Mailjet is generally considered a reliable email service provider with good email deliverability rates.  However, like any email service provider, deliverability can vary depending on factors such as list quality, email content, and sending practices. Mailjet provides tools and resources to help users maintain a good sending reputation and maximize email deliverability.

How are Mailjet’s transactional and marketing emails different?

Mailjet handles transactional and marketing emails separately. Transactional emails are triggered by specific user actions, such as order confirmations or password resets, and are sent individually.

Marketing emails are sent to groups of subscribers and are typically used for promotional purposes or newsletters. Mailjet allows users to manage both types of emails within the same platform but with distinct features and settings.
