Kit vs Mailjet
Both stand on email marketing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Pick Kit if you want newsletter publishing with paid subscriptions, sponsor marketplace access, or API access. The free plan provides up to 10,000 subscribers, while Creator and Pro are listed for 1,000 subscribers at their stated monthly prices. Consider another option if the free plan’s single basic Visual Automation or the paid plans’ listed subscriber basis does not suit your needs.
Visit KitChoose Mailjet for combined marketing and transactional email, with automation, developer sending tools, and team collaboration in one platform. The free plan has a daily sending cap, while paid plans start at $9 a month and unused credits do not roll over.
