How to Import Contacts for Cold Outreach Campaigns

Your outreach is only as good as your list. Learn how to import CSV contacts, optionally get Apollo.io-powered suggestions from your campaign settings, and keep data clean before launching a JacSend campaign.

9 min readUpdated June 2026

Cold email campaigns fail when lists are bloated, outdated, or sourced without permission. JacSend keeps list building simple: import your own CSV, add contacts to campaigns, or optionally request contact suggestions matched to your campaign industry, persona, and goal.

This guide covers CSV format, plan contact limits, deduplication, Apollo.io suggestion boundaries, and list hygiene before you activate sends.

CSV import for outreach contacts

Export contacts from your CRM, spreadsheet, or research tool as CSV and import into a JacSend campaign. Include email as the required field; add name, company, and custom columns you want AI drafts to reference.

Plan limits cap total contacts: 25 on Free, 200 on Starter, 1,000 on Pro. Build focused lists within those caps rather than importing everyone you might someday email.

List quality beats list size

Two hundred well-targeted contacts outperform ten thousand random addresses. Filter by role, industry, company size, and trigger events before import. Remove generic inboxes like info@ unless you have a specific reason to pitch there.

  • Verify emails are current and role-relevant
  • Remove duplicates before upload
  • Exclude competitors and existing customers unless intentional
  • Segment different ICPs into separate campaigns
  • Never import purchased lists without lawful basis

Optional Apollo.io contact suggestions

JacSend can suggest B2B contacts by querying Apollo.io based on your campaign industry, target persona, and goal. Available on Starter and Pro plans with monthly limits. Results save to your account only, never shared with other users.

Suggestions are not permission to contact anyone. You must confirm a lawful basis before adding them to a campaign. JacSend does not scrape websites or verify data from Apollo.io.

Deduplication and blocklists

JacSend deduplicates contacts within your account to avoid double-sending. When someone replies or declines, mark them on the dashboard; they auto-blocklist from future sequences. Maintain the blocklist for manual opt-outs too.

Organizing contacts into campaigns

Free and Starter plans allow one campaign each; Pro allows up to five. Split campaigns by offer, persona, or geography so AI briefs and copy stay coherent. Each campaign runs its own 4-touch sequence and send queue.

Pre-activation checklist

Before activating: preview AI drafts for several contacts, confirm SMTP is connected, accept campaign consent confirming you may outreach these people, and verify you are within plan send and contact limits.

Frequently asked questions

What columns should my CSV include?
At minimum, email. Name, company, title, and any personalization fields improve AI drafts. Use UTF-8 encoding and standard comma separation.
Does JacSend integrate with Apollo.io?
Yes. Optional contact suggestions are powered by Apollo.io. JacSend sends your campaign criteria to Apollo.io and stores matching results in your private account. You can also import contacts from any source via CSV.
Are my contacts visible to other JacSend users?
No. Contacts you upload or add via suggestions are private to your account.
What are contact suggestion monthly limits?
Free plans do not include contact suggestions; import your own list. Starter allows 6 suggested contacts per month; Pro allows 30. Limits reset at the start of each UTC calendar month. Up to 10 contacts may be suggested per request.
Can I import the same contact into multiple campaigns?
Be cautious: duplicate outreach across campaigns annoys prospects. JacSend deduplicates within your account; prefer one active sequence per contact.
