Prepare before sending
Check domain authentication, sender readiness, recipient status, template content, unsubscribe handling, and sending strategy before a campaign goes live.
RSender
Coming soonOperate authorized email campaigns with control at every step
RSender is a desktop email-operations console for sending identities, permissioned contacts, templates, campaigns, automation, suppression, queue control, and delivery analysis.
The problem
Bulk email operations become difficult when account health, DNS authentication, recipient consent, templates, queue behavior, bounces, unsubscribes, and reports live in separate tools or spreadsheets.
RSender brings those responsibilities into one operational workspace while keeping suppression and unsubscribe enforcement visible.
Core value
Control active delivery
Observe the queue and SMTP response stream, adjust global strategy, pause or resume campaigns, and stop all sending when investigation is required.
Keep compliance in the workflow
Suppressed and unsubscribed contacts are skipped across sending paths. Changes are reflected in operational history instead of being treated as an optional afterthought.
Features
Domains and DNS
Add sending domains, review suggested SPF/DKIM/DMARC records, recheck authentication, and inspect domain-specific detail.
Sending accounts
Add or import SMTP accounts, configure server and TLS details, store credentials locally, test connectivity, pause accounts, and review health.
Contacts and segments
Import CSV data, map fields, deduplicate, compare against suppression, add tags, create rule-based segments, and manage subscription state.
Email templates
Create or import HTML templates, use variables and dynamic content, preview output, manage link-variable sources, and maintain an unsubscribe path.
Campaigns
Choose recipients, template strategy, send strategy, and compliance preflight. Start, pause, resume, duplicate, inspect, and export campaigns.
Automation flows
Build workflows from source, action, decision, wait, and end nodes. Select templates and sending accounts, save the graph, and control draft, running, or paused states.
Queue and strategy
Review live delivery logs and queue totals, apply global rate and timing settings, enable automatic throttling, pause/resume, or stop sending.
Suppression and unsubscribe
Manage hard-bounce, soft-bounce, complaint, unsubscribe, and manual suppression records. Sending paths enforce suppression checks.
Deliverability and reports
Review recipient-domain outcomes, delivery-rate trends, bounce reasons, engagement measures where entitled, and campaign/account/domain breakdowns.
Workflow
- Activate RSender on the operating device.

- Choose template and send strategy.
- Complete the compliance preflight.
- Start the campaign and monitor the queue.
- Review delivery results and update suppression when required.
Use cases
- Permission-based lifecycle and announcement campaigns
- Product updates to opted-in users
- Authorized customer communication across several SMTP accounts
- Segmented campaigns with reusable templates
- Operational review of delivery, bounce, and suppression behavior
Local data, security, and compliance
SMTP credentials remain on the local Go side of the application and are not stored by the browser UI. Activation and selected optional hosted services require network access.
RSender does not remove the user's responsibility to obtain permission, identify the sender, provide working unsubscribe mechanisms, honor requests, protect credentials, and follow provider rules and applicable law.
Product relationship
Use MailFleet when you need to deploy supported server software, and RS Email Verifier when you need a separate list-quality assessment. RSender does not automatically pull assets or results from those products.
FAQ
Is RSender an email account provider?
No. You configure authorized SMTP sending accounts and domains.
Can suppression checks be disabled for a campaign?
Suppression is enforced across sending paths and is not presented as a campaign-level bypass.
Does RSender guarantee inbox placement?
No. Delivery depends on permission, content, authentication, sender reputation, provider policy, recipient behavior, and other external factors.
What happens when the license expires?
Sending actions are locked while read-only access and the relevant renewal or recovery guidance remain available according to the current license state.
