FAQ
Mailjet starts at Free versus SparkPost's $20. Because pricing models differ by tier, the cheaper option depends on your monthly volume, so compare the pricing rows in the scorecard above.
Mailjet's paid plans start at USD 9 per month for the Starter tier, which includes 8,000 emails per month and removes the free plan's daily sending limit. Higher tiers such as Essential and Premium add automation, segmentation, and dedicated IP options, and custom enterprise pricing is available. Pricing scales primarily by email volume.
On current Bird pricing, signup provides a test API key for evaluation rather than an ongoing free production allowance. SparkPost historically offered a free monthly volume for some accounts, but the published Bird email plans now start with the paid Starter tier. Teams needing a permanent free sending quota should confirm current terms directly with Bird.
