Key Differences

The main things that set these tools apart

Platform Scope

SMTP Specialization

Overview

Mailjet and SMTP2GO serve different purposes in the email space. Mailjet (owned by Sinch) is a unified platform combining transactional email, marketing campaigns, and collaboration tools. SMTP2GO is a dedicated SMTP relay service focused on reliable email delivery. The choice depends on whether you need a full platform or just delivery infrastructure.

Different Tools for Different Needs

Mailjet gives you everything: transactional API, marketing campaigns, visual builder with collaboration, automation workflows. SMTP2GO gives you one thing done well: reliable SMTP relay with strong deliverability. Neither approach is wrong. The right choice depends on your needs.

SMTP Relay Specialization

SMTP2GO focuses entirely on email delivery. Dedicated IPs on all paid plans, managed IP reputation, detailed delivery reporting. If your primary concern is getting emails delivered reliably, SMTP2GO's specialization shows. Mailjet offers SMTP but as one of many features.

Marketing Capabilities

Mailjet includes marketing campaigns, visual email builder with real-time collaboration (Passport), automation workflows, contact management, and segmentation. SMTP2GO has none of these features. For businesses needing both transactional and marketing email from one vendor, Mailjet is the only choice here.

Pricing Structures

Pricing models differ significantly. SMTP2GO charges by email volume, with $50/month for 100,000 emails. Mailjet charges by contacts with email limits per plan. For high-volume transactional-only sending, SMTP2GO can be more cost-effective. For moderate volumes needing both transactional and marketing, Mailjet offers better value.

Dedicated IP Access

SMTP2GO includes dedicated IP options on all paid plans. Mailjet reserves dedicated IPs for Premium plans. If dedicated IP is important for your deliverability strategy from day one, SMTP2GO makes this more accessible.

The SaaS Alternative

SaaS companies often need more than pure delivery or basic marketing. Sequenzy offers unified marketing and transactional built for SaaS, with native Stripe integration and behavioral automation neither platform provides.

Making the Choice

Choose Mailjet for unified email platform with marketing and collaboration features. Choose SMTP2GO for dedicated SMTP relay with deliverability focus. For SaaS with marketing automation and transactional emails with Stripe integration, consider Sequenzy.
