Broadcasts

Create a Broadcast

A broadcast is a one-time email campaign. Use broadcasts for newsletters, product announcements, event invitations, launch emails, policy updates, promotions, or any message you want to send one time to selected subscribers.

1. Click Broadcasts in the left sidebar to open the Broadcasts page for the workspace that should send the campaign.
2. Click Create Broadcast in the page header.
3. In the Select Email Template drawer, choose a blank starting point, a saved Email Template, or an admin starting point template.
4. On the Compose step, enter the Subject that subscribers will see in their inbox.
5. Add Preview Text when you want many email apps to show a short snippet below or beside the subject.
6. Write the email message in Body. Use Switch Template only when you want to replace the current starting point with another template.
7. Click Save Broadcast in the header to keep the draft without moving to the next step, or click Continue when the email content is ready for delivery settings.

Broadcasts usually follow this workflow: create the draft, write the email, preview the design, choose subscribers, select delivery settings, send a test email, and then send now or schedule the campaign for later.

Compose and Preview

The compose step controls what subscribers will see in the email. Start with a blank email, an admin-provided starting point, or one of your saved email templates. Use the email editor to add text, images, buttons, spacing, dividers, and sections.

• Subject line: the main inbox text. Write a specific subject so subscribers understand why the email matters.
• Preview text: the short inbox snippet shown next to or below the subject in many email apps. Use it to add context instead of repeating the subject.
• Body content: the email message. Keep the main purpose clear, and avoid adding too many competing calls-to-action.
• Links and buttons: check that every URL opens the intended page. Use meaningful button text instead of vague wording.
• Personalization: use subscriber data only when you are confident the fields are present and accurate for the target subscribers.

Preview the broadcast in both desktop and mobile layouts. A design that looks good on a wide screen can still have awkward spacing, oversized images, or long button text on a phone.

1. From Broadcasts, click the draft you want to edit.
2. On the Compose step, write or edit the Subject, Preview Text, and Body.
3. Add links, buttons, images, and personalization only where those elements support the main goal.
4. Use desktop preview to check layout and spacing on wider screens.
5. Use mobile preview to check text wrapping, button width, and image size on small screens.
6. Open every important link before sending a test email.
7. Click Save Broadcast before you leave the editor.

For concept guidance before you write the email, use Write the Subject and Preview Text, Write the Email Body, and Email Headers and Message Format.

Subscribers and Delivery

The subscriber selection step controls who receives the broadcast. The delivery step controls which email delivery connection sends the broadcast. Review both steps carefully because a polished email sent to the wrong subscribers is still a bad campaign.

• Include tags: send the broadcast to active subscribers who have the selected tags.
• Include segments: send the broadcast to subscribers who match saved live rules.
• Exclude tags: remove subscribers who should not receive this message, such as customers who already purchased or subscribers who opted out of a topic.
• Status protection: Mailrith avoids normal marketing sends to subscribers who are unsubscribed, bounced, complained, blocked, or otherwise not eligible.
• Delivery connection: choose the enabled sender assigned to the workspace. The selected connection controls From name, From email, provider, and delivery event tracking.

Check the subscriber count before sending. If the count is much larger than expected, your selection may include too many subscribers because of broad OR logic or a missing exclusion. If the count is much smaller than expected, review the selected tag, segment, subscriber status, and workspace.

1. Open the broadcast draft and click Continue from the Compose step to reach the Send step.
2. In Connection, choose the Email Delivery Connection assigned to the current workspace.
3. Enter a Reply To Email if replies should go to an address other than the sender address.
4. In Recipients, choose the tags or Segments for the subscribers who should receive the campaign.
5. Add exclusions for subscribers who should not receive the campaign.
6. Review the subscriber count and compare it with the number you expected.
7. Open or preview the segment if the subscriber count looks wrong.
8. Confirm that the From name and From email match the sender details subscribers should see.
9. In Tracking, review the defaults from Workspaces > Edit Workspace > Privacy & Consent, choose whether to keep Track Opens and Track Link Clicks enabled for this broadcast, and fill UTM fields only when your reporting system needs them.

For high-risk campaigns, create a segment first and preview the matching subscribers before you select the segment in the broadcast. A saved segment makes the rules easier to review and reuse.

If you need to decide how the sender, reply address, tracking, and UTM fields should work together, read Choose Delivery Settings, From, Reply-To, and Return-Path, and Tracking Domains, Links, and UTMs.

Test, Schedule, and Send

Always send a test email to a real inbox before you send the broadcast to subscribers. If possible, open the test email on desktop and mobile. Check the subject, preview text, images, links, buttons, personalization, spacing, footer, and unsubscribe link.

After you finish testing, choose the send option:

1. On the Send step, use the test email area to send a test email to yourself and at least one reviewer.
2. Open the test email on desktop and mobile.
3. Check the subject, preview text, images, buttons, links, personalization, footer, and unsubscribe link.
4. Return to the broadcast and fix any content or design problem you find.
5. Review the final subscriber count and delivery connection again.
6. To send later, turn on Schedule Broadcast, choose a future date and time, then click Schedule.
7. To send immediately, leave Schedule Broadcast off and click Send Now. The broadcast will show as sending while Mailrith delivers it in the background.
8. Confirm the send only when the campaign content, selected subscribers, and send time are correct.

• Save Broadcast: use this option when the copy, design, subscriber selection, or approvals are not finished.
• Schedule: choose a future time based on the workspace timezone. Review the timezone carefully when subscribers are in another region.
• Send Now: start delivery to the selected subscribers. You can leave the page while Mailrith keeps sending.

After a broadcast starts sending, you cannot edit it or recall emails that have already been submitted to your delivery provider. You can request cancellation to stop Mailrith from preparing and submitting the remaining emails. If you find a problem before the scheduled send time, cancel or edit the scheduled broadcast before delivery starts.

After sending, review sent count, opens, clicks, unsubscribes, bounces, and complaints. These numbers depend on tracking settings and delivery webhook events, so make sure the delivery connection is configured correctly.

1. Open Broadcasts from the left sidebar.
2. Find the sent broadcast you want to review.
3. Click the bar chart Broadcast Statistics button in that broadcast's row.
4. Use Download in Clicks by Link or Subscriber Activity when you need the full CSV. Mailrith prepares the file in the background and emails you a download link when it is ready.

If this is a new sender or a larger-than-usual campaign, review Sending Volume and Warmup and Inbox Placement, Promotions, and Spam Folders before sending broadly.

Send and Monitor a High-Volume Broadcast

After Mailrith approves and enables high-volume sending for a workspace, Mailrith can prepare and process a Broadcast for one million Subscribers through its high-volume delivery system. Your email provider still controls how many emails your account can send each day and how quickly it can send them. Mailrith cannot raise those limits or recall an email the provider already accepted. Mailrith cannot guarantee that an email will reach the inbox instead of another folder.

High-volume sending is not enabled for every workspace. Contact Mailrith support before planning a Broadcast for one million Subscribers, and do not start the campaign until support confirms that the workspace and delivery connection are approved and enabled.

Understand the Readiness Checks

• Daily quota: the number of emails your provider allows during its rolling or calendar-day quota window. The remaining quota must cover the selected Subscribers after any safety reserve.
• Send rate: the number of emails your provider allows each second. A lower rate makes the Broadcast take longer, but it does not mean Mailrith is stuck.
• Production access: permission from the provider to send real campaigns. A restricted or sandbox account may send only to approved test addresses.
• Sender authentication: DNS records and provider checks that show the From domain is allowed to send. Mailrith reports the sender status that the connected provider can verify, but this does not replace checking SPF, DKIM, DMARC, and any provider-required setup before a large campaign.
• Warmup: a gradual increase in sending volume that helps providers learn to trust a new sender. An approved quota for one million emails does not mean a new sender should use all of it immediately.
• Event webhook health: the provider connection that reports accepted, delivered, bounced, and complained events back to Mailrith. Fix missing event reporting before a large send.
• Estimated duration: Mailrith's current estimate based on the Subscriber count and safe provider rate. The estimate can change when the provider slows the connection or the remaining quota changes.

Run Preflight and Start Sending

1. Click Broadcasts in the left sidebar.
2. Open the draft you want to send.
3. Finish the Compose step, then click Continue to open Send.
4. In Connection, select the email delivery connection approved for this campaign.
5. In Recipients, review the selected tags, Segments, exclusions, and final Subscriber count.
6. In Tracking, review open tracking, link tracking, and UTM settings.
7. Send a test email and check the message, links, personalization, footer, and unsubscribe link.
8. Click Send Now. Mailrith checks the current Subscriber estimate, provider access, quota, rate, the sender status available from the provider, and event setup.
9. If Confirm High-Volume Broadcast opens, compare the workspace, Broadcast subject, Subscriber estimate, connection, and estimated duration with your approved send plan.
10. Click Confirm And Start Sending only when every detail matches. Return to the Broadcast if anything is wrong.

Monitor Delivery Progress

1. Click Broadcasts in the left sidebar.
2. Click the Broadcast with the Sending status to open Broadcast Statistics.
3. Review the accepted and prepared totals, Retrying, Skipped, Failed Or Unknown, Effective Rate, Estimated Completion, and Last Progress.
4. Review the percentage complete. If Failed Or Unknown is greater than zero, click Inspect Delivery Errors to distinguish failed results from unknown results.
5. Leave the page open for automatic updates, or return later. Mailrith continues sending in the background.

Prepared means Mailrith created delivery work for those Subscribers. Accepted means the provider accepted the email for delivery. Accepted does not guarantee inbox placement. Retrying means Mailrith has a safe reason to try later, such as a temporary provider response or a capacity wait. Skipped means a current Subscriber protection, such as an unsubscribe, suppression, bounce, complaint, or consent rule, stopped submission.

Respond to a Provider Pause

A provider pause does not always mean the Broadcast failed. Mailrith pauses new submissions when the provider's safe rate or daily capacity is not available. The progress panel explains the reason and shows when Mailrith plans to check again. Do not start a second Broadcast for the same Subscribers.

1. Open the sending Broadcast in Broadcast Statistics.
2. Read Sending Is Paused and the pause reason.
3. Check the next retry time when it is shown.
4. If the message asks you to fix production access, authentication, or connection setup, click Email Delivery Connections in the left sidebar, then click the selected connection's row.
5. Contact your provider when the account quota or send rate is lower than the provider approved.
6. Wait for automatic recovery after capacity returns. Contact Mailrith support if the next retry time passes without new progress.

Cancel Remaining Delivery

Cancellation stops Mailrith from submitting remaining emails. A provider request already in progress can still finish, and an accepted email cannot be recalled.

1. Open Broadcasts, then open the sending Broadcast in Broadcast Statistics.
2. Click Cancel Sending.
3. Read the warning in Cancel Broadcast Sending.
4. Click Cancel Broadcast to continue, or Keep Sending to close the dialog.
5. Wait for Cancellation Requested. Mailrith safely finishes in-progress requests and cancels remaining eligible work.
6. Review the final accepted and prepared totals after processing finishes. Give support the Broadcast ID if the exact canceled total is needed.

Inspect Failures and Unknown Delivery

Permanent failure means the provider definitively rejected the email and another automatic attempt is not useful. Unknown means Mailrith cannot prove whether the provider accepted the email. Retrying an unknown email can send a duplicate, so Mailrith does not automatically retry it without verified provider protection.

1. Open Broadcasts, then open the completed Broadcast in Broadcast Statistics.
2. Find Sent With Errors in the progress panel.
3. Click Inspect Delivery Errors.
4. Review each paginated item in Delivery Errors.
5. Give Mailrith support the Broadcast ID, approximate time, provider, error code, and whether the outcome is Failed or Unknown. Do not send provider credentials or Subscriber personal data in a support message.
6. Do not manually resend unknown deliveries. Support must escalate unknown outcomes for provider reconciliation and duplicate-risk review.

How Subscriber Protection Works During a Large Send

Mailrith checks current eligibility again before provider submission. A Subscriber who unsubscribed, bounced, complained, became blocked, lost required consent, or is currently suppressed is skipped even if the Subscriber matched when preparation began. Provider bounce and complaint events continue to update the normal Subscriber and suppression systems after accepted email leaves Mailrith.

For a new domain, new IP, or much larger volume than usual, follow Sending Volume and Warmup. For authentication and inbox placement guidance, read From, Reply-To, and Return-Path and Inbox Placement, Promotions, and Spam Folders.
