Send Cold Email Campaigns That Actually Land
Multi-account round-robin sending, contact personalization, and built-in email authentication — everything you need to reach the inbox, not the spam folder.
Cold Email Campaigns in 3 Steps
From domain check to delivered campaign — no technical expertise required.
Upload Your Contacts
Import your prospect list via CSV or paste contacts directly. Celeric reads first name, last name, and email so every message feels personal.
Write & Personalize
Use {{first_name}} and {{last_name}} variables in your subject and body. Send yourself a test email before launching the campaign.
Send with Round-Robin
Connect multiple SMTP accounts and Celeric distributes your contacts automatically across them — reducing per-account volume and protecting your sending reputation.
Bad Authentication Kills Cold Email Deliverability
Most cold email tools ignore authentication. Celeric monitors SPF, DKIM, and DMARC so your emails pass inbox filters before you hit send.
SPF
SPF tells receiving mail servers which IP addresses are authorized to send cold email on behalf of your domain — without it, your messages look suspicious before they're even opened.
DKIM
DKIM cryptographically signs each cold email so inbox providers can verify the message hasn't been tampered with in transit — a key signal that separates legitimate senders from spammers.
DMARC
DMARC ties SPF and DKIM together and tells Gmail, Yahoo, and Outlook what to do when authentication fails — required by all major providers for bulk and cold email senders.
