Schedule Newsletters

In SentinMail, a newsletter is simply a campaign sent to a subscriber list on a schedule. There's no separate "newsletter" feature — you use the same tools you already know: templates, lists, and scheduled sends.

This means you have full flexibility — send weekly roundups, monthly updates, product announcements, or any recurring email to any list, on any schedule.

Create a dedicated list

Go to Audience → Lists and create a list for your newsletter (e.g., "Weekly Newsletter", "Product Updates").

Write a great description

The list description is shown on your public subscribe page. Write something subscribers will understand: "Get weekly tips, product news, and exclusive offers delivered every Friday."

Build your template

Go to Content → Templates and create a template for your newsletter. Use the Visual Builder for a polished design, or Basic mode for simple HTML.

Use [[variables]] for personalization:

[[first_name]] — subscriber's name
[[unsubscribe_url]] — one-click unsubscribe link (always include this)

Grow your list

Share your subscribe page link so people can opt in to your newsletter:

Code

txt

1```
2https://sentinmail.app/subscribe/YOUR_COMPANY_ID
3```

Visitors will see your list with its description and can choose to subscribe. You can find this URL on your Dashboard.

Schedule the send

Go to Send → To List and fill in:

Campaign Name — e.g., "Weekly Newsletter — April 4, 2026"
Email Template — select your newsletter template
SMTP Configuration — your sending server
Subscriber List — your newsletter list

Toggle Schedule and pick the date and time you want it sent.

Click Schedule Campaign.

Success

Your newsletter is scheduled! It will be sent automatically at the specified time. You can check its status or cancel it from the Campaigns page.

Use Descriptive Campaign Names

Name your campaigns with the date or issue number so they're easy to find later:

"Weekly Newsletter — Week 14, 2026"
"Product Update #12 — April 2026"
"Monthly Digest — March 2026"

Your subscribe page at https://sentinmail.app/subscribe/YOUR_COMPANY_ID is always live. Add it to:

Your website footer
Social media bios
Email signatures
Blog posts and landing pages

Subscribers choose which lists to join, so you can have multiple newsletters running to different lists from the same subscribe page.

Scheduling Best Practices

Monitor Performance

After each newsletter send, check:

Open rate — are people reading your emails?
Click rate — are people engaging with your content?
Unsubscribe rate — are you losing subscribers? A spike means something's off.
Bounce rate — clean your list if bounces are high.

Go to Dashboard for charts or Campaigns → Sent Emails for per-recipient details.

Managing Multiple Newsletters

You can run multiple newsletters from the same company:

Create a separate list for each newsletter (e.g., "Weekly Tips", "Product News", "Community Events")
Write clear descriptions for each list — these appear on the subscribe page
Subscribers choose which lists to join when they sign up
Schedule each newsletter independently via Send → To List

Info

When subscribers visit your subscribe page, they see all your lists with descriptions and can pick exactly which ones they want. This reduces unsubscribes because people only get what they asked for.

Using the API to Schedule Newsletters

If you want to automate newsletter scheduling (e.g., from a CMS or content pipeline), use the API:

Code

bash

1curl -X POST https://api.sentinmail.app/api/emails/send/to-list/ \
2  -H "X-API-Key: fm_your_api_key_here" \
3  -H "Content-Type: application/json" \
4  -d '{
5    "name": "Weekly Newsletter — April 4, 2026",
6    "template_id": "YOUR_TEMPLATE_UUID",
7    "smtp_config_id": "YOUR_SMTP_CONFIG_UUID",
8    "list_id": "YOUR_LIST_UUID",
9    "scheduled_for": "2026-04-04T09:00:00Z"
10  }'

See the Dev Guide: Sending Emails for full API documentation.
