From a local shop to a multi-brand enterprise. We set up your authentication, keep your sending reputation isolated from other senders, and watch it every day, so order confirmations, invoices and newsletters reach your customers instead of their spam folder.
No servers to run. Works with anything that sends over SMTP: WordPress, WooCommerce, your CRM, booking or billing software.
A five-person shop, a 200-person company and a global organization all have different email problems. Pick yours.
Usually the right fit: Essentials, up to 50,000 emails a month.
Usually the right fit: Growth, or Dedicated above a million emails a month.
Usually the right fit: Enterprise, designed around your organization.
It's rarely your message. Most delivery problems start in the infrastructure underneath it.
Cheap relays and web-host mail put many senders on the same IP addresses. When one of them spams, mailbox providers distrust everyone on that address, including you.
Without correct SPF, DKIM and DMARC records, Gmail, Outlook and Yahoo can't confirm the email really came from your business, so they play it safe and filter it.
Reputation slips slowly: a spike in bounces, a batch of complaints, a list that aged badly. Without monitoring you find out when customers stop replying.
Since 2024, Gmail and Yahoo require businesses that send in volume to meet authentication and complaint standards. Microsoft has followed with similar rules for Outlook. Every SMTPCart setup meets them from day one.
A clear process, so you know what happens next and what we need from you.
We look at your domains, current setup and what you send, then tell you honestly what's causing problems and what fits.
Day 1We assign your isolated environment and help you add SPF, DKIM and DMARC. You get SMTP credentials to plug into your tools.
Days 1 to 3New IPs and domains start gently. We ramp your volume on a schedule mailbox providers trust, instead of blasting on day one.
Weeks 1 to 4We watch delivery, bounces, complaints and blocklists continuously and adjust before small issues become spam-folder problems.
Every day after

Dependable outbound mail for your customers without becoming deliverability experts yourselves.
Smart-host relay
Your web host's mail is cheap, and self-serve relays like Amazon SES and SendGrid are excellent if you have someone to run them. SMTPCart is for businesses that want inbox delivery without doing that work themselves.

Already on SES or SendGrid and happy? Keep it. Most teams come to us when they outgrow shared pools, or no longer have time to manage reputation themselves.
Get a free deliverability checkWhen hundreds of people and dozens of systems send email in your name, delivery becomes a governance problem as much as a technical one. SMTPCart Enterprise gives IT, security and each business team what they need.
Your reputation is only as clean as the senders around you. So every SMTPCart customer goes through the same review, and the same rules apply to everyone.
We check your use case, domains and list practices before you send a single email.
Permission-based email only. It protects you, and every other customer on our network.
Bounce, complaint and blocklist signals are tracked continuously, and we act on them the same day.
Message content and contact lists are processed only to deliver your email, never sold or shared.
SMTP is the standard way software sends email. Managed SMTP means we run the sending servers, set up the authentication and look after your reputation. You get a server address, a username and a password, put them into your website or app, and we make sure the email gets delivered.
If your tool can send through SMTP, yes. That covers WordPress (through any SMTP plugin), WooCommerce, most CRMs, booking systems, billing tools and custom applications. We'll help you connect it and send a test first.
Yes. The only step on your side is adding a few DNS records to your domain. We'll walk you through it on a call or send exact copy-paste values for your registrar, then confirm everything is working.
Most small businesses are sending within a few days of the assessment. If you need a new dedicated IP, we warm it up gradually over a few weeks, and you can send reduced volumes throughout.
Your cost depends on real factors: volume, whether you need dedicated IPs, how many domains you send from and how much management you want. We quote after the assessment, and the quote holds. No overage traps and no surprise throttling.
Yes, to people who have agreed to hear from you. We don't accept purchased, rented or scraped lists. On Growth and Dedicated plans, marketing runs on a separate stream so it never affects your receipts and password resets.
Yes. On Enterprise we complete security questionnaires, sign data processing agreements, and agree service levels and payment terms in the contract. Tell us what your process requires and we'll plan around it.
Yes. We run your new environment alongside the current one, move lower-risk streams first, and switch critical mail like password resets and invoices only once delivery is proven. Nothing is cut over until it's stable.
Usually we notice first. We investigate the cause, whether that's a list issue, a content pattern or a provider change, fix what's on our side and tell you clearly what to change on yours.
Tell us a little about how you send. A specialist will review your domain and reply with what's affecting your delivery and the setup we'd recommend.
