What is an SMTP relay service?
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.
Is there a free plan?
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.
When can I start using MailerAce?
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.
Do I need to change my code?
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.
Can I send marketing or bulk email?
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.
Is there a free trial on paid plans?
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.
How do you count emails?
One email is one recipient. A message sent to three recipients counts as three emails.
Which ports and encryption do you support?
Port 587 with STARTTLS and port 465 with implicit TLS on smtp.mailerace.com. Unencrypted authentication is never accepted.
Why does my account start in sandbox mode?
Every new account starts in a sandbox where you can only send to your own verified domains and team members. It lets you integrate right away while keeping spammers off our shared IPs. Accounts are reviewed and approved quickly, usually automatically.
Do you offer dedicated IP addresses?
Yes, as an add-on from the Pro plan and included on Scale. We help you warm the IP up gradually so mailbox providers learn to trust it.
What happens if I go over my monthly emails?
Paid plans keep sending and bill extra emails at the overage rate shown on the pricing page. The Free plan stops at its limit until the next month.
Do pay-as-you-go credits expire?
Credits are valid for 12 months from purchase. There is no monthly fee.
Where is my data stored?
Our infrastructure runs on dedicated servers in professional data centres. See the Privacy Policy and Subprocessors pages for providers and locations.
Can I cancel at any time?
Yes. Paid plans can be cancelled at any time and stay active until the end of the billing period. See the Refund Policy for money-back terms.
Is there an HTTP API?
An HTTP sending API with batch sending and idempotency keys is coming soon. Today, SMTP works with every language and framework.
Still curious?
Ask for early access and try the platform with your own domain.
