## Pricing, features, and summaries

1

### Instantly

Cold email infrastructure and reply help

Instantly leads because an AI email agent, in the searches that convert, is usually cold outbound: mailboxes, warmup, and a campaign that sends. Growth starts at $47 a month. It is a bad fit for a newsletter to customers you already have.

Instantly pricing and features/Instantly alternatives

2

### lemlist

Cold email with a built-in lead database

lemlist is both the data and the sender. The email plan is shown from $55/mo. Use it when you do not already have Apollo. Use Instantly or Smartlead when you do.

lemlist pricing and features/lemlist alternatives

3

### Apollo

Sequences on top of Apollo's own data

Apollo's email is a sequence tool welded to the database. It ranks second on access and integrations. Use it when the list and the send should be the same seat. Use Instantly when mailbox volume is the actual problem.

Apollo pricing and features/Apollo alternatives

4

### Reply.io

Cold email priced by active contacts

Reply prices email by how many people you can start a sequence with. The annual floor is $49 per user for 1,000 active contacts. Multichannel, which adds LinkedIn, starts higher. Bring a list if the included data credits are not enough.

Reply.io pricing and features/Reply.io alternatives

5

### HubSpot Breeze

Email to people already in the CRM

Breeze is the marketing-email and CRM-email row. Job fit is lower than Instantly because this page's demand leans outbound, and higher than a pure writing tool because the send and the record are in one place.

HubSpot Breeze pricing and features/HubSpot Breeze alternatives

6

### Smartlead

High-volume cold email infrastructure

Smartlead is the mailbox layer. Base is $39/mo in the pricing FAQ, with a trial and unlimited connected accounts on the plans they describe. Bring your own list.

Smartlead pricing and features/Smartlead alternatives

7

### Artisan Ava

Autonomous outbound email

Ava will email as a BDR. That is a real email agent and a custom-priced one. It beats Copy.ai on the tie-break because job fit is higher. It loses to Instantly because you can buy Instantly without a demo.

Artisan Ava pricing and features/Artisan Ava alternatives

8

### Copy.ai

Drafting the message, not sending it

Partial fit. Copy.ai writes the email. Something else has to own the domain, the warmup, and the unsubscribe. Do not rank a writer as a sending platform.

What users say

An older Trustpilot review says Copy.ai helped with product descriptions.

Later reviews say logins stopped working, support did not answer for months, and saved prompts disappeared after an update.

- “Copy Ai is great. It helped me a lot with my product description. But ever since I upgraded, the composition is shorter compared to my free trial.”Trustpilot

- “It had a paid subscription and used it a bit, but my login stopped working. Reached out to support via email and via the website form. No response for months even after several messages.”Trustpilot

- “I was an enthusiastic used and ambassador. then the service just stopped working. nothing works.”Trustpilot · A.F.

## What is an AI email agent?

An AI email agent in this list is mostly cold outbound: mailboxes, warmup, and sequences. AI agents for email that write a message and do not send it, such as Copy.ai, are a different product and are labeled that way.

AI email marketing to people who already know you sits closer to the CRM. HubSpot is that row. The rest of the page is cold sending.

## How AI email marketing tools work

Instantly and Smartlead rotate sending across mailboxes you connect. You bring the list. Apollo and lemlist can supply the contacts and the sequence in one seat. Reply prices email by active contacts and can add LinkedIn, calls, and an AI SDR named Jason on higher plans. Artisan Ava is the autonomous BDR, with no public price.

Copy.ai writes the message. It does not send it. A human still owns the offer, the list, and the domain.

## Features of an AI email agent

Cold infrastructure and a marketing inbox are different risks. Do not buy one and expect the other.

- Mailbox warmup and campaign sending for cold email

- Sequences tied to a contact database, when you want both

- A human on the offer, the list, and the domain

## Benefits of AI agents for email

You can send at a volume one inbox cannot carry, and you can keep the writer separate from the sender.

- Send at a volume a single inbox cannot carry

- Keep the list and the sequence in one seat when that is simpler

- Avoid buying a writer and calling it a sending platform

## Who uses AI email marketing tools

Outbound teams, and CRM teams emailing contacts they already store. An assistant that triages a personal inbox is on the personal assistant list, not here.

## AI email agent pricing

Instantly Growth starts at $47/mo. Apollo has a free plan, then $49/user/mo billed annually. HubSpot's free CRM includes the Breeze assistant. Artisan Ava is custom. Copy.ai Chat is $29/mo and writes the message. It does not send it. Smartlead's FAQ lists Base at $39/mo. lemlist shows an email plan from $55/mo. Reply Email Volume starts at $49 per user/month billed annually.

Reply's month-to-month floor for 1,000 active contacts is $59 per user. The $49 figure is annual billing. Last checked 5 October 2026.

## How to choose an AI email agent

Choose Instantly or Smartlead for cold mailbox infrastructure. Choose Apollo or lemlist when the database and the sequence should be the same seat. Choose Reply when you want a published contact-tier price and a 14-day trial. Choose HubSpot for people already in the CRM.

Do not buy Copy.ai expecting it to send.
