Infrastructure Built for Bulk

Instead of just buying an SMTP server, you're buying a complete system designed to keep your server alive and hitting inboxes.

Dedicated Server

High inbox placement with IP rotation, SPF/DKIM/DMARC configuration. The best SMTP for marketing.

100% Privacy

Zero content monitoring. We accept all types: bulk marketing, transactional, and promotional emails.

AI Sender Software

Includes our 2026 Pro Software with AI copywriter, auto-warmup, and 250M+ B2B contacts database.

Instant Setup

Don't wait hours. Our automated provisioning gets you up and running in minutes, not days.

Why Do SMTP Servers Die?

Most users lose their server in 24 hours because they blast 10,000 emails in 5 minutes without protection. Here is how our Bulletproof Method fixes it forever.

The "Burn & Block" Cycle

Aggressive speed spikes trigger ISP "bot filters" instantly. Your IP gets greylisted, then permanently blocked.

The "Bulletproof" Method

Our software mimics human behavior (1 email every 15-45s). Flies under the radar of Gmail/Outlook filters.

Auto IP Rotation

If an IP reputation dips, our system auto-rotates to a fresh, pre-warmed one instantly.

AI Spam Checker

The software scans your body for spam triggers & cleans your list of bounces before sending.

250M+ B2B Contacts

Built-in lead database so you can start sending campaigns immediately without buying lead lists.

Simple, Transparent Pricing

No caps, no overages, no hidden fees. Choose your power level.

Frequently Asked Questions

What exactly do I get when I buy?
You get full access to a dedicated SMTP relay server pre-configured with SPF, DKIM, and DMARC. If you choose the bundle, you also get our AI-powered cold email software and access to our 250M+ B2B contact database.
What does 'unlimited' actually mean?
Unlimited means we don't charge you per email sent. There are no hard caps on your monthly sending volume. However, we advocate for "fair-use" speeds using our slow-timed sending technology to ensure your IP reputation remains high and emails land in the primary inbox.
Is it suitable for affiliate or bulk marketing?
Yes! Unlike many providers (like Amazon SES or Mailgun) who strictly monitor content and ban accounts for affiliate offers, LocalSMTP has zero content restrictions. We believe in complete privacy and freedom for your marketing campaigns.
How quickly can I start sending?
Setup typically takes less than 5 minutes for Instant SMTP accounts. Custom Domain SMTP takes slightly longer (usually under an hour) to propagate DNS records. Everything is automated to get you live as fast as possible.
