You're in the right place if
You searched for a way to send newsletters at scale without being gouged on pricing per contact. You want control over your sending domain and inbox reputation, not another platform that locks you into their pricing model.
Why Your Current Platform Caps Your Outreach
Most email marketing tools charge per message sent or tier you into send limits that reset monthly. When your list hits 10,000 contacts and you want to run a weekly newsletter, those constraints become a bottleneck that costs you both reach and revenue.
The real issue isn't capacity—it's pricing architecture. You're paying a premium to rent someone else's sending infrastructure, which means they control what you can send and what you pay per send. The moment your list grows, your costs grow proportionally, even if your sending infrastructure could handle the volume without issue.
For operators running outbound campaigns, this model breaks down. You need to reach your full list, not a limited slice of it.
Send From Your Own Infrastructure—No Caps, No Per-Email Fees
Connect your SMTP provider and IMAP mailbox to the platform and send at the volume your infrastructure supports. There are no artificial caps on sends, and you're not charged per email dispatched.
This approach puts deliverability control in your hands. Your sender reputation lives on your domain, not a shared platform domain that other users might degrade. If you already have a dedicated SMTP service you trust, you keep using it—your sending reputation stays intact, and you avoid the reputation risk of moving to a new shared IP.
For high-volume senders, this is the difference between paying for the contacts you have and paying for the emails you actually send.
Build Campaigns in Plain Text or HTML
The campaign editor lets you create newsletters in plain text or HTML, depending on what your audience expects. Plain-text emails often perform better for cold outreach—higher open rates, fewer spam filter triggers, more personal feel. HTML newsletters work well for brand-forward campaigns where visual layout matters.
You don't need to export to a separate design tool or hire a developer. The editor handles both formats, and you can preview how each version renders before launching. For cadence sequences that start with a polished HTML newsletter and follow up with plain-text check-ins, you build the entire flow in one place.
This flexibility matters when you're A/B testing subject lines or adjusting format based on audience response rates.
Reply-Until-Response Cadences That Run Automatically
Set up sequences that continue sending follow-ups until a recipient replies. This model works for cold outreach where you're pushing toward a conversation, not just a click. Each step in the cadence triggers based on the previous action—or inaction—allowing you to nurture prospects without manual intervention.
Track opens, clicks, bounces, and unsubscribes per step. When a recipient replies, the sequence stops and flags that contact for follow-up. When a recipient unsubscribes, they're automatically excluded from further sends. You get full visibility into what's working and where prospects are dropping out of the flow.
This automated model scales without requiring you to manually manage individual follow-ups across a large list.
Protecting Inbox Placement as You Scale
High send volume only matters if your emails land in the inbox. Using your own SMTP and IMAP gives you control over sender authentication—SPF, DKIM, and domain reputation sit with your domain, not a shared platform IP that other senders might damage.
Monitor bounce rates and unsubscribe rates to catch deliverability problems early. High bounce rates signal to inbox providers that your list hygiene may be slipping; catching and removing invalid addresses quickly protects your reputation. The platform tracks these metrics per campaign so you can intervene before a problem affects your broader sender score.
Scaling outreach responsibly means matching volume to infrastructure quality. When you own your sending stack, you decide how fast to ramp and how to manage reputation as your list grows. Related guides: Chatbot and AI chatbots.
