Mailgun 批量发送电子邮件在否时不起作用。收件人超过 2000

Question

我用来通过Mailgun Api发送批量邮件的这个功能，它在没有时工作。收件人的数量小于 1000，但收件人大于 2000 时失败。

我正在做的是，我正在获取收件人列表，然后将它们分成 5 组（1 批邮件中的 5 位收件人）。批量邮件包含各种内容占位符（%recipient.name%），在从 Mailgun 发送批量邮件时，这些占位符会被原始数据替换，此外，我还在批量邮件中添加一些自定义数据以跟踪 Mailgun 日志中的邮件

.

/**

 * @param text $subject content mail subject
 * @param text $text content mail in text body
 * @param array $from sender details
 * @param array $recipients content all recipients details
 * @param text $htmlBody content mail html content
 * @param int $type content mail type
 * @param int $broadcastId batch mail id
 * @param int $broadcastType type of broadcast email
 * @param int $isUser content user or contact
 * @return boolean

        $broadcastType = '', $isUser = '')

    //get the broadcast mailgun info
    $this->_mgClient = apiKey;
    $this->_domain = domain;

    // divide batch mail in chunk of 5(sending 5 emails in 1 batch mail)
    $recipientsArr = array_chunk($recipients, 5);

    try {
        foreach ($recipientsArr as $allRecipient) {
            $batchMsg = $this->_mgClient->BatchMessage($this->_domain);

            // Define the subject.

            // Call finalize() to send any remaining recipients still in the buffer.
            $batchMsg->finalize();
        }
        // finalize doesn't return anything. so if dont through any error, its a success
        return true;
    } catch (Exception $ex) {
        error_log($ex->getMessage());
        return false;
    }

}

根据他们的文档 (https://documentation.mailgun.com/user_manual.html#batch-sending)，允许批量发送的最大收件人数量为 1000，因此请将您的批次控制在此范围内。
