Who should choose which
Choose Instantly if
- email is your main channel and you want volume: Instantly lists unlimited email accounts and plans up to 500,000 emails a month.
- you want warmup inside the sending tool: unlimited warmup is listed on its plans.
- you want an AI that answers email replies and books through a Calendly link, with the option to approve each one first.
- you need a link to Pipedrive or Salesforce today. Instantly lists Pipedrive, and Salesforce through a third party tool, while Sellinger shows both as coming soon.
Choose Sellinger if
- your buyers are on LinkedIn or WhatsApp as well as email, and you want one agent and one conversation history instead of a separate LinkedIn tool.
- you want the agent to research each prospect, write every message, answer replies and book the meeting.
- you want deals, contacts and each conversation in a built in CRM that syncs both ways with HubSpot.
- you want a database of 700M+ contacts and LinkedIn intent signals under the same login.
What it costs for email, AI replies and LinkedIn
Instantly sells sending, AI and data as separate subscriptions: Outreach for emails and contacts, Credits for the AI Reply Agent and lead searches, and a CRM add on. Sellinger prices by module, with the agent that writes and replies inside each one.
The table uses monthly list prices in US dollars. Instantly Growth lists 5,000 emails a month, and each Sellinger email tier has its own message limit on its pricing page, so volume is not like for like.
- Instantly credits expire 2 months after purchase on monthly plans. It lists no overage charge: when included volume runs out, you move up a tier.
| What you need | Instantly | Sellinger |
|---|---|---|
| Email sending, entry plan | $47 (Outreach Growth, 5,000 emails) | $39 (Email Starter, agent included) |
| Email with AI replies | $94 (Outreach Growth $47 plus Credits Growth $47) | $39 (Email Starter, agent included) |
| Email, AI replies and LinkedIn | $94 plus a LinkedIn tool bought separately, not priced here | $249 (Outbound bundle: LinkedIn plus email) |
Who writes, replies and books
Instantly's AI Reply Agent reads each reply on an email thread, answers questions and objections, shares a Calendly link and logs the result to the CRM. The pages we checked show it on email only.
Sellinger's agent studies each prospect, writes the opening message and each follow up, handles the replies and books the meeting, across LinkedIn, WhatsApp and email. A campaign can hold every message for approval, and a person can take over any conversation.
Sending volume and deliverability
This is where Instantly leads. It lists unlimited email accounts, unlimited warmup, volume up to 500,000 emails a month, dedicated IP rotation on Light Speed and inbox placement tests in the trial.
Sellinger's emails leave through a mailbox you connect, and the sending domain is yours to set up. Each account has daily limits the agent cannot exceed, and email defaults to 50 sends a day per mailbox. Daily limits sit on each mailbox, so a plan that needs thousands of emails a day from many domains fits Instantly better.
Switching between Instantly and Sellinger
You can run both for a while if each tool uses its own mailboxes and its own LinkedIn accounts.
- Connect a mailbox in Sellinger that Instantly does not use, and set up its sending domain.
- Upload a CSV of leads or search the contact database, then describe your offer and approve the first messages.
- Add a LinkedIn or WhatsApp account if you want those channels, which the Instantly pages we checked do not list natively.
- Give it a few weeks, then compare replies and meetings per mailbox before moving more volume.
- Sequences, warmup history and credits in Instantly do not move across. We have not checked what Instantly exports.
- Unused Instantly credits expire 2 months after purchase on monthly plans, so plan your stop date.
