メール配信サービスのトップ3

Resend comes first: a free plan of 3,000 emails a month with 30 days of logs, then $20 a month for 50,000. Amazon SES grades higher, as $0.10 to $0.16 per 1,000 emails is well under the others, but new accounts start in a sandbox and setup runs through AWS, so it is second. Mailjet is third for shops that want newsletters on the same plan. Mailtrap narrowly missed: it also charges $20 at 50,000, but its free plan allows 1 domain and 3 days of logs. SendGrid is $19.95 for 50,000 with no lasting free plan and 1 teammate.

   2位: Amazon SES

   無料トライアル

   Apps on AWS, or sending in volume 向け

   Amazon SES sends and receives email for apps through an API, SMTP or AWS SDKs, with address validation, shared or dedicated IPs and rules for routing incoming mail. There is no monthly fee: the à la carte rate is $0.10 per 1,000 emails, and Essentials, where new accounts start, is $0.16. It is second because it is slower to start: new accounts sit in a sandbox that only sends to verified addresses until AWS approves a limit increase, there is no free monthly allowance beyond up to $200 of credits for new AWS customers, and setup runs through code and the AWS console.

   3位: Mailjet

   無料プラン · $8.10/月 から

   Shops sending order emails and newsletters 向け

   Mailjet sends receipts and password resets through an API or SMTP relay and newsletters through a drag-and-drop editor, from one account and one plan, with webhooks, a parse API for inbound email, EU data centers and connections to WordPress, WooCommerce and Shopify. The free plan sends 6,000 emails a month with no card, and Starter is $8.10 a month billed yearly ($9 monthly) for 8,000 with no daily limit. It is third because app email alone costs more: 50,000 emails is $40 a month on Essential, billed monthly, against $20 on Resend. The free plan stops at 200 emails a day, and online support lasts only the first month.
