Cold Email Campaigns

Campaigns let you send personalized emails to a list of contacts using your own SMTP accounts. Celeric handles delivery, tracks progress, and lets you retry failures.

Before you start: You need at least one Sending Account configured and some Contacts in your pool.

Creating a campaign

1. Go to Campaigns in the sidebar

2. Click + New Campaign (or use the Quick create form at the top of the list)

3. Enter a Campaign name (internal reference) and a Subject line

4. Click Create Campaign — you'll be taken to the campaign editor

---

Writing your email

Subject line

The subject line supports merge tags that are replaced with each contact's data:

Example: Hey {{first_name}}, quick question about {{email}}

Email body

The body textarea supports the same merge tags. Write your email as plain text. The same {{first_name}}, {{last_name}}, {{full_name}}, and {{email}} tags work here.

Autosave: Changes to the subject and body are saved automatically after you stop typing. You'll see a "Saving..." then "Saved" indicator.

Adding contacts

You can add contacts to a campaign in two ways (only available when the campaign is in Draft status):

Option 1 — Paste

Click + Paste to open a text input. Paste emails in any of these formats:

# One per line:
john@example.com
jane@example.com

# With names (CSV):
john@example.com,John,Smith
jane@example.com,Jane,Doe

# From a spreadsheet — tab-separated also works

Option 2 — Browse

Click Browse to open your contact pool and select contacts:

• Search by name, email, or company
• Filter by health status (Healthy, Risky, Invalid, Unknown)
• Check individual contacts or click Select all
• Contacts already added to the campaign are shown as grayed out
• Click Add N to Campaign to confirm

---

Selecting sending accounts

In the Sending Accounts section of the campaign editor, check one or more accounts to use for sending.

• One account — all emails are sent from that account
• Multiple accounts — contacts are distributed round-robin across accounts (first contact → account 1, second → account 2, etc.)

If you haven't set up a sending account yet, there's a link to Sending Accounts to add one.

---

Pre-send checklist

Before you can send, all four items in the checklist must be complete:

• Subject written
• Body written
• At least 1 contact added
• At least 1 sending account selected

Incomplete items are shown in red. The Send Campaign button stays disabled until all are green.

---

Sending a test email

Before sending to your full list, test how the email looks:

1. Enter your own email address in the Send a test field

2. Click Send Test

3. Check your inbox — the email uses your actual subject and body with example merge tag values

If you don't receive it, check spam or verify your sending account works via Test connection.

---

Sending the campaign

1. Click Send Campaign

2. Confirm in the dialog that appears

3. Celeric begins sending in the background — you'll see a live progress indicator showing sent and failed counts

What happens during send:

• Emails are sent sequentially through your selected sending accounts in round-robin order
• A small delay is added between sends to avoid rate limiting
• The campaign status changes to Sending while in progress, then Sent when complete

You can navigate away while the campaign is sending — it continues in the background.

Monitoring progress

While a campaign is sending, the page polls for updates every few seconds. You can see:

• Sent count — successfully delivered
• Failed count — could not be sent (SMTP error or invalid address)
• Total — total contacts in campaign

After sending completes, a summary shows the final totals.

---

Retrying failed contacts

If some contacts failed, click Retry Campaign (or Retry Failed Contacts) to re-attempt delivery to only the failed contacts. The campaign uses the same sending accounts as the original send.

---

Deleting a campaign

From the campaign list, campaigns can be deleted. Deleting a campaign removes it and all its contact send records from your account.
