Frequently Asked Questions

Common questions about our SMTP infrastructure.

What is an SMTP server?
SMTP (Simple Mail Transfer Protocol) is the standard protocol for sending emails across the internet. An SMTP server is a computer program that sends, receives, and relays outgoing email messages between sender and receiver mail servers. CloudMails provides professional SMTP infrastructure with high deliverability rates and dedicated IPs.
What is the difference between shared and dedicated SMTP?
Shared SMTP uses the same IP addresses among multiple customers, which means your sender reputation can be affected by others' behavior. Dedicated SMTP gives you exclusive use of IP addresses, so your reputation depends only on your own sending practices. Dedicated SMTP is recommended for high-volume senders and cold email campaigns.
How many emails can I send through CloudMails SMTP?
Depending on your plan, you can send from 50,000 to unlimited emails per month. Our infrastructure handles high-volume sending with automatic load balancing across multiple IPs to maintain deliverability and sender reputation.
What is IP warming and why is it important?
IP warming is the process of gradually increasing email volume on a new IP address to establish a positive sender reputation with mailbox providers. Starting too fast can get your IP blocklisted. CloudMails provides guided IP warming support and automatic warmup scheduling to protect your reputation.
How does CloudMails ensure email deliverability?
CloudMails ensures deliverability through multiple layers: dedicated IPs with pristine reputation, automatic SPF/DKIM/DMARC configuration, real-time bounce processing, spam score monitoring, and direct relationships with major mailbox providers including Google, Microsoft, and Yahoo.
Can I use CloudMails SMTP for cold email campaigns?
Yes, CloudMails SMTP infrastructure is specifically optimized for cold email outreach. We provide dedicated IPs, inbox rotation, warmup services, and compliance tools to maximize deliverability while respecting anti-spam regulations including CAN-SPAM and GDPR.
What authentication methods do you support?
CloudMails supports full email authentication including SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance). These are automatically configured for all domains and can be customized through your dashboard.
Do you offer API access?
Yes, all plans include REST API access for integrating SMTP functionality into your applications. The API supports sending email, managing templates, retrieving analytics, and controlling IP rotation. Full API documentation is available for Professional and Enterprise plans.
