Email outreach and connect by email

Warmerly
Cold email sequences from Gmail, Outlook, Zoho or SMTP, with a reply inbox for email and LinkedIn. No connect by email.
Octopus CRM
No email sequences listed. Connect by Email sends connection requests by email to pass LinkedIn's weekly limit.
The short answer
Email outreach and connect by email, in one look.
Warmerly is a cold email tool first: it sends sequences from Gmail, Outlook, Zoho or SMTP mailboxes, with a daily limit for each mailbox, a volume ramp, a bounce brake and pre-launch checks, and replies from email and LinkedIn land in one inbox. Octopus CRM has one email feature on its pages, Connect by Email, which it says sends connection requests by email so you can pass LinkedIn's weekly invite limit, and it describes no email sequences, mailbox connections or sending limits. Warmerly has no connect-by-email feature. Last checked 21 October 2026.

Emails a day from one mailbox
Warmerly's campaign ramp, from 3 a day, up 1 a day, to 15
WarmerlyOctopus CRM
- Warmerly: 3 a day on sending day 1, 1 more each day, 15 by default. The default limit for each mailbox is 30 a day, and the ramp can only tighten it.
- Octopus CRM: no email sending is described, so no line is drawn.
A sending day is a day in the campaign's sending days, so weekends hold the cap flat. A bounce rate of 7% pauses the mailbox.

How Warmerly does it
Warmerly, in detail.
A full email campaign engine: sequence steps, scheduling, a 30 a day default for each mailbox, a ramp from 3 to 15 a day, a bounce brake from 2 per cent, and 13 kinds of pre-launch check.
01
A daily limit for each mailbox: 30 by default
Each mailbox has its own daily campaign limit, 30 by default, and a campaign has its own daily limit field, also 30 by default. Sending is not metered on paid plans. The Free plan allows 100 campaign sends a month.

02
A volume ramp from 3 to 15 a day
A campaign can ramp each mailbox from 3 emails on sending day 1, adding 1 a day, up to 15 by default, so full volume arrives on the 13th sending day. It is switched on automatically for young mailboxes, and it can only tighten a mailbox's limit, never raise it.

03
A bounce brake before the pause
Over a rolling 7 days, below 2 per cent bounces a mailbox is untouched. From 2 per cent its daily cap is multiplied by 0.75, from 3 per cent by 0.5 and from 5 per cent by 0.25. At 7 per cent the mailbox is paused. None of it applies under 25 sends.

13 kinds of pre-launch check
The readiness table lists 13 kinds of check before Start: 7 that block (such as no usable step, no sender, no queued leads, an unknown merge tag) and 6 that warn (such as no postal address, a DNS warning, a free mailbox still waiting, spam-style copy). A warning needs one acknowledgement.

05
Replies and unsubscribes
A genuine reply stops the lead's sequence by default, and unsubscribes go on a workspace-wide suppression list. The inbox's default view is Needs reply, and a suggested reply under 120 words can be drafted for the latest inbound email.

Where Warmerly is behind
Warmerly does not send LinkedIn connection requests by email, and we found nothing like it. It does not bypass a LinkedIn limit. LinkedIn steps and email steps sit in one sequence, but email carries its own deliverability rules.

How Octopus CRM does it
Octopus CRM, in detail.
Connect by Email is the only email feature described. It is presented as a way round LinkedIn's weekly invitation limit, not as an email channel.
01
What Connect by Email is
The home page says Octopus CRM lets you bypass LinkedIn's weekly invite limit and send a higher volume of connection requests per week by email, without any risk to your LinkedIn account. It appears under the heading Connect by Email.

02
The suggested way to use it
The FAQ calls one of the most effective strategies sending 100 regular connection requests a week and, once you reach the weekly limit, switching to sending connection requests by email.

03
Repeated across its pages
The same offer is repeated on the auto connect, lead generation, prospecting, sales solutions and auto invite pages, each with the same wording. The tutorial page lists a video titled Bypass Weekly Invite Limit on LinkedIn.

A name that is not about email
The page titled LinkedIn Mailer describes automated messages and follow-ups to prospects on LinkedIn, not email. It names the First name, Last name, Company and Position variables and says to watch your response rate.

Its claim about risk
The claim of no risk to your LinkedIn account is the vendor's statement. We found no page that explains how the email is sent, from which address, or how it relates to LinkedIn's own rules.

What Octopus CRM does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Email sequences, follow-up emails or scheduling
- Which mailbox or address the connection email is sent from
- How the recipient's email address is obtained
- A daily or weekly limit for connection emails
- A reply inbox for email replies
- Unsubscribe handling or a suppression list for email
- Whether Connect by Email is on every tier
Where the sources disagree
We report each version rather than pick one.
- The page named LinkedIn Mailer describes LinkedIn messages, while the home page's Connect by Email describes email. We read the first as LinkedIn messaging because of its own text.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
The two email features answer different questions
Octopus CRM's is a way to invite people to connect when LinkedIn will not let you send more. Warmerly's is a channel of its own, with its own sender reputation to protect.
Ask Octopus CRM how the email leaves
If the email comes from your own mailbox, its reputation is yours, and the mailbox needs warming. If it comes from Octopus CRM, you would want to know from whom. The pages do not say.
Unsolicited email has its own rules
This is a plain explanation, not a finding about Octopus CRM: email to people who have not asked to hear from you is covered by laws such as PECR in the UK and CAN-SPAM in the US. Warmerly's pre-launch checks warn when a campaign has no postal address.
Do not treat the weekly limit as a puzzle to solve
Warmerly's LinkedIn caps are lower than the 100 a week Octopus CRM quotes. A tool that sends more is not automatically safer, and a limit that is passed by another route is still LinkedIn's limit.
Who it suits

Octopus CRM
