Definition
Definition: An SMTP outreach platform sends campaigns through mail infrastructure you control (Gmail, Outlook, SendGrid, Postmark, etc.) while tracking engagement and bounces in one place.
Capabilities
Each capability maps to a workflow you can run in the product today.
Provider flexibility
Use the inbox your client already pays for or a transactional provider you trust. No forced relay subdomain.
Campaign orchestration
Sequences, throttling, and pauses without rebuilding mail merge sheets each week.
Deliverability visibility
See bounces and engagement per campaign. Pause quickly when a list or subject line underperforms.
Shared workspace
Lists, enrichment, and sends live together so operators are not exporting CSVs between tools.
How it works
- 1
Publish DNS records
SPF, DKIM, and DMARC on the sending domain before meaningful volume.
- 2
Connect SMTP in settings
Use app passwords or API keys per your provider documentation. Send a test message.
- 3
Warm the domain
Low volume in week one. Increase only when hard bounces stay minimal.
- 4
Run campaigns with caps
Daily send limits protect reputation. Raise caps when metrics stay healthy.
Quick answers
Short answers to common search queries about this topic.
Why not use a shared sending pool?
Shared pools hide whose content hurt reputation. Owning SMTP keeps accountability with your domain and your copy.
Is Gmail SMTP enough?
Yes for many SMB operators at moderate volume. Heavier volume often moves to SendGrid or Postmark for reporting APIs.
Deliverability controls
Kyrolane includes test mode and campaign stats, but DNS and warmup discipline still live with your team.
- Dedicated subdomain for cold mail when possible
- Plain-text multipart for critical first touches
- Remove hard bounces immediately from active lists
Agency client setup
Document which domain sends for each client. Separate projects in Kyrolane keep lists and metrics from bleeding together.
In-depth guide
SMTP outreach in plain language
You already have email infrastructure: Google Workspace, Microsoft 365, or a transactional provider. An SMTP outreach platform plugs into that infrastructure to send sequences, track engagement, and keep lists in sync with what actually sent.
Kyrolane is not an inbox provider. It is the campaign layer on top of inboxes you control.
DNS checklist (copy for clients)
| Record | Purpose | |--------|---------| | SPF | Lists allowed senders for the domain | | DKIM | Cryptographic signature per message | | DMARC | Policy for failed alignment |
Publish all three before cold volume. Use a subdomain when the root domain also sends transactional mail.
Provider notes
Gmail / Google Workspace: App passwords or OAuth depending on your setup. Watch daily limits for consumer-grade accounts.
Microsoft 365: SMTP AUTH must be enabled by admin.
SendGrid / Postmark: Strong for agencies managing multiple clients with separate subaccounts.
Warmup schedule example
| Week | Daily sends per inbox | |------|----------------------| | 1 | 15 to 20 | | 2 | 25 to 35 | | 3 | 40 to 60 | | 4+ | Scale if bounces under 2% |
Pause if hard bounces spike or spam complaints appear.
Test mode workflow
- Create campaign with five test accounts you control
- Send preview batch
- Check rendering on mobile Gmail and Outlook
- Confirm tracking pixels fire
- Switch to live list
Job applications use the same SMTP
Candidates and agencies benefit from one configuration. Job application emails and cold campaigns share reputation on the same domain, so split domains when job volume and cold volume are both high.
