Alibaba Cloud Direct Mail

Alibaba Cloud Direct Mail is an email sending service for transactional notifications and batch email, run on Alibaba Cloud so a business can send without building its own mail server. It handles both kinds of mail: triggered messages such as registration confirmations, order confirmations, password resets and transaction notifications, and batch mail such as product promotions and journal subscriptions. The product page describes Direct Mail as a key product for Alibaba's own e-commerce platforms and says tens of millions of emails are sent through it every day by Alibaba and Alibaba Cloud customers.

That internal use is the product's main credential. The page says Direct Mail handles system notifications, member promotions and user surveys for Tmall, all registration, notification, promotion and survey mail for Taobao, and registration and transaction notifications for buyers and sellers on Alipay. For both Tmall and Taobao it is described as the only mailing channel during the Double 11 shopping festival.

How sending works

There are three ways to send. The administration console lets a user create sending addresses without opening mailboxes in advance, upload recipient lists, create templates, send batch email and view statistics; the console supports batch sending only, not triggered mail. The API covers developers through the Alibaba Cloud SDK, with a SingleSendMail call for up to 100 recipients and a BatchSendMail call that sends to one uploaded recipient list. The SMTP interface is the standard route for existing applications: each sender address gets its own SMTP password, set in the console, and the documentation carries SMTP examples for Java, Python, C#, PHP, Perl, Ruby, Node.js and Go alongside an SDK guide and an API reference.

Templates handle personalization, and console recipient lists carry variables such as UserName, NickName, Gender, Birthday and Mobile. A queuing and scheduling mechanism manages delivery, and a strategic mailing function controls sending frequency. The product page lists outbound mail redundancy across multiple servers and databases, and high-concurrency processing, among its benefits. The documentation index also lists a Direct Mail MCP service, a monitoring service, RAM-based access control, a warming-up guide, Gmail delivery help, advice for preparing bulk sends and a summary of common email return codes.

Reporting covers the number of requests, successfully sent emails, failed emails, invalid addresses, delivery rate and labeled mail, and real-time statistics can be queried by sender address and email tag. Statistics data is retained for 30 days.

Domains and setup

Each account can add up to 5 sending domains, and the FAQ recommends using two of them to keep triggered and batch mail apart. It also recommends a second-level domain rather than the top-level one. An existing enterprise mailbox domain should not be used directly, because the MX record needed for domain validation would conflict with the mailbox's own MX record, but a subdomain of it can be. A domain and all its subdomains can belong to only one Alibaba Cloud account. Direct Mail provides no inbox, so its sending addresses cannot receive mail.

Quotas and limits

The limits page is detailed. Each account starts with a daily quota of 2,000 emails, adjusted according to sender reputation, and the monthly quota is the daily quota times 30. An account can have 100 sender addresses, which cannot be edited but can be deleted, up to 10 a month. It can hold 10 recipient lists of up to 10,000 addresses each, depending on the daily quota, plus 100 templates and 500 email tags of up to 128 characters. Template subjects are capped at 256 characters and bodies at 1 MB, and IP protection accepts 10 IP addresses or ranges.

Attachments work through SMTP and through the API with the latest SDK, but not through the console. An email, attachments included, cannot exceed 15 MB, with at most 100 attachments. Because Base64 encoding makes files 1.5 times larger or more, the page advises keeping attachments to 8 MB or less and using a download link for anything bigger.

Pricing

Direct Mail is billed by the number of emails sent, with two payment methods. Pay-as-you-go costs $0.29 USD per 1,000 messages, calculated to two decimal places with a minimum billing fee of $0.01 and no minimum usage fee. Resource packages are prepaid for a 6-month service period: 50,000 messages cost $13.05, 500,000 cost $121.8, 1 million cost $230.55 and 5 million cost $1,123.75, and the table shows the saving against pay-as-you-go for each. Mail is deducted from the package that expires first, billing switches to pay-as-you-go once all packages are used, and unused package resources cannot be refunded. The product page also advertises a new-user offer of $7.00 for 50,000 messages.

Each primary account gets a one-time free quota of 2,000 emails, usable at up to 200 a day. Dedicated IPs are a prepaid add-on that keeps a sender's reputation apart from other users: the pricing page offers them in Hangzhou, Singapore, Germany (Frankfurt) and USA (Virginia), shows $128 for 1 month, and says the service currently supports monthly subscription with automatic renewal. Email Verification, a separate pre-send check of whether each address is syntactically correct, exists and can receive mail, is sold in packages valid for one year, from 10,000 checks for $70 to 1,000,000 for $3000, with discounts of up to 57% on the larger sizes.

Support and service terms

The documentation index includes a Direct Mail Service Level Agreement. The product page advertises an upgraded support package with 1-on-1 presale consultation, 24/7 technical support, 6 free tickets per quarter and an after-sale response time cut from 36 hours to 18 hours. Sales can be reached by live chat or through a business development contact in the customer's region, and technical issues go through tickets.

Who it suits

Direct Mail fits businesses already on Alibaba Cloud, and developers who want a per-message sending service with a clear quota model, for registration mail, order confirmations, password resets and transaction alerts over API or SMTP. The console suits scheduled batch mail such as promotions or subscription newsletters to an uploaded list. Per-thousand pricing and prepaid packages keep costs predictable at volume, and the free quota covers testing.

The trade-off is that it is sending infrastructure rather than a marketing suite: an account holds 10 lists of up to 10,000 addresses each, and the starting daily quota of 2,000 grows only with sender reputation, so a new account ramps up gradually.
