SendGrid and Mailjet both serve developer-oriented use cases with strong API access, but genuinely differ in their broader feature emphasis beyond pure transactional sending.
If your primary need is proven, high-volume transactional infrastructure, SendGrid's longer track record matters. If your team also collaborates directly on marketing campaigns, Mailjet's collaborative editing is a genuinely useful, distinctive addition.
Pricing varies by specific volume and feature tier — direct comparison at your actual sending volume is the most reliable way to determine relative cost.
Mailjet offers solid deliverability, though SendGrid's longer track record specifically at very high transactional volume gives it a modest edge for the most demanding use cases.
Yes, both include marketing campaign functionality, though this remains secondary to their core transactional and developer-focused strengths.
