How it works
No mail server to run, no IP reputation to build alone. We handle authentication, routing and bounces.
Add the domain you send from. We create its DKIM key and show the DNS records to publish.
Publish the records with your DNS host. We check automatically and tell you exactly what is missing.
Copy the username and password into your app, mail plugin or framework config, using smtp.mailerace.com.
Your mail is signed, routed through warm IPs and delivered. Webhooks tell your app what happened.
Developers
If your stack can send email, it can send through MailerAce. Copy five settings and you are live, in any language, framework, CMS or no-code tool.
SMTP_HOST=smtp.mailerace.com
SMTP_PORT=587 # STARTTLS (or 465 for TLS)
SMTP_USER=acme_prod_8f2k
SMTP_PASS=••••••••••••••
MAIL_FROM="Acme <[email protected]>"Platform
Built by people who have chased bounced password resets at 2 a.m. Every feature exists to get mail delivered and to tell you what happened.
Point any app at smtp.mailerace.com on port 587 or 465 with TLS. No SDK to install, no code to rewrite.
We generate 2048-bit DKIM keys, give you the exact DNS records, and check them for you until your domain is verified.
Separate credentials per app, limited to the domains you choose and, if you like, to your server IPs. Rotate without downtime.
Get events delivered to your endpoint with an HMAC signature, automatic retries and a delivery log you can replay.
Shared pools managed for reputation, or dedicated IPs with guided warm-up. Transactional and bulk mail never share IPs.
Hard bounces and complaints are suppressed so you stop sending to addresses that hurt your reputation.
Invite teammates with roles (owner, admin, developer, viewer) and keep each project in its own workspace.
Send with a single JSON request, batch sending and idempotency keys.
Per-message events and dashboards for delivery, opens and clicks.
Reputation, protected
Every new account starts in a recipient sandbox and is reviewed before sending to the world. Purchased lists are banned. Bounces and complaints are suppressed automatically. That discipline is what keeps inbox placement high for everyone.
New accounts send only to their own verified domains until approved.
Transactional and bulk mail use different IP pools.
DKIM signing, SPF alignment and DMARC checks on every domain.
Rate limits, outbound spam scanning and automatic pauses on abuse signals.

An SMTP relay accepts email from your application over the standard SMTP protocol and delivers it to recipients on your behalf, from IP addresses with a good sending reputation and with proper authentication (DKIM, SPF, DMARC). It replaces running your own mail server.
Yes. The Free plan includes 3,000 emails per month (up to 100 per day) with one verified sending domain. It will open first, before paid plans, and needs no card.
MailerAce is in its final pre-launch phase. Email [email protected] for early access and we will let you know as soon as accounts open.
No. Any app or framework that can send email through SMTP works: WordPress, Laravel, Django, Rails, Node.js, PHP, and most SaaS tools with an SMTP setting.
MailerAce is built for transactional email first. Opt-in bulk mail is supported on plans with the broadcast stream, which uses separate IPs and requires one-click unsubscribe headers. Purchased or scraped lists are never allowed.
Yes. Every paid plan starts with a 3-month free trial with the plan’s full monthly volume. You are not charged during the trial and can cancel any time before it ends.
One email is one recipient. A message sent to three recipients counts as three emails.
Accounts open soon. Ask for early access and be among the first to send.
