CritSend's SMTP Relay Service for AWS Customers
CritSend has stepped in to help AWS EC2 customers send their mail reliably. Our easy to use enhanced SMTP relay service takes the burden of deliverability management off of our customers. All with no AWS out-of-network fees and no sending limits.
Ensuring Email Delivery for AWS Customers
Amazon Web Services customers have come to us with special deliverability needs. Spamhaus, MAPS, and other RBL blacklist providers had flagged a large block of AWS's EC2 IP addresses, preventing many AWS customers from sending their legitimate emails. In addition, all Elastic IP users are having reverse DNS lookup issues impacting deliverability with major ISPs.
Our Deliverability Engine automatically handles compliance, authentication, headers, full unsubscription management, bounce processing and more through our whitelisted servers. Our online dashboard makes customization easy. CritSend's filters catch and alert you of emails perceived as spam before they are sent. Your legitimate transactional email, password reminders, invoices, newsletters, and social network notifications reach their destinations and you never worry about IP blacklisting or reputations again. CritSend's online analytics track opens, click-thrus, spam folder reports, hard and soft bounces, unsubscriptions and more.

To save Amazon Web Services customers any out-of-network fees and to benefit from EC2 's low latency cloud, we have placed connecting servers within the EC2 server cloud. Your mail is then shuttled to CritSend's own cluster distributed throughout multiple redundant and replicated servers in several geographically dispersed data centers. It is automatically analyzed by our Deliverability Engine, reassembled with necessary authentication and deliverability additions, then delivered to your recipient's ISP.
CritSend is a pay-per-use delivery service. There are no contracts, you pay only for the emails you will send. At $1 per 1,000 emails our price is far below the competition. CritSend fully scales for your changing traffic needs, and our load balanced servers smoothly handle sudden increases in sending quantities. We provide seamless traffic handling during your startup website launches, newsletter campaigns, invoice billing cycles and other traffic bursts that result from your success.
