MailCore is a professional bulk email marketing platform for organizations that need to send large campaigns through dedicated SMTP infrastructure. Its service supports up to 5 million sends per day, with plan volumes of 5 million or 20 million emails to be used within 30 days. Features include automatic rotation of sending IPs, domains, subjects, and sender addresses, plus configured rDNS, SPF, DKIM, and DMARC authentication.

Customers can upload multiple mailing lists, use the platform’s corporate-list storage, schedule campaigns, personalize messages with placeholders, and apply filters and segmentation options. MailCore also provides campaign-writing prompts and technical support via Signal and email. The company offers two paid plans, Alfa and Ômega, and does not provide free trials.

Plans are priced at R$1,000 and R$4,000 respectively, with payment accepted by Pix or USDT. Customers register through an online form; MailCore’s team then supplies payment and access instructions, and access is released after payment confirmation
