The short answer
Emails per month on the starting plan, in one look.
Warmerly's paid plans have no monthly send meter, but each mailbox has a daily campaign limit (30 by default), which is about 4,500 a month on Starter's 5 mailboxes once they are established. Smartlead Base lists 6,000 emails a month, and sending stops when the allowance runs out until the next reset or an upgrade. Above about 150 emails a day Smartlead Base sends more in a month, until it uses its 6,000 allowance at 200 a day and stops; at or below 150 a day the two behave much the same. Last checked 19 October 2026.

| Pace | Warmerly Starter (5 mailboxes, 30 a day each) | Smartlead Base (6,000 emails) |
|---|---|---|
| 100 a day | 3,000 sent, inside the 150 a day ceiling | 3,000 of 6,000 used, no stop |
| 150 a day | 4,500 sent, exactly at the ceiling | 4,500 of 6,000 used, no stop |
| 200 a day | 4,500 sent, held to 150 a day | 6,000 of 6,000 used by day 30 |
| 300 a day | 4,500 sent, held to 150 a day | 6,000 sent, stops after day 20 |
| 400 a day | 4,500 sent, held to 150 a day | 6,000 sent, stops after day 15 |
Lines are drawn from the published numbers and a steady pace you choose. A dotted line shows the pace you asked for when a limit holds it back. Real sending varies by day. Smartlead also has a Messages per day setting on each mailbox, recommended at 40 to 50 including warm-ups.
What a month of sends reaches
Contacts you can work through in a month, by how many emails each contact gets in your sequence.

How Warmerly does it
Warmerly, in detail.
Paid plans do not count sends. The cap is per mailbox per day, so volume follows the number of mailboxes.
01
No monthly send meter on paid plans
campaignSends is unset on Starter, Growth and Agency, meaning no monthly send cap. The plan blurb says sending is never metered.

02
Daily limit per mailbox
Each mailbox has a daily campaign limit, default 30, which can be changed. The ramp and the reputation brake can tighten it further.

03
What that means on each plan
At the default limit, 5 mailboxes send 150 a day, about 4,500 a month; 25 mailboxes send 750 a day, about 22,500; 100 mailboxes send 3,000 a day, about 90,000. This is our arithmetic, assuming every mailbox sends the default limit every day of a 30 day month. The code comment gives the 4,500 figure for 5 mailboxes.

04
Free plan is capped
The Free plan keeps a send cap of 100 as an abuse guard.

05
Why there is no meter
The code comment says metering sends on top of a daily limit only punished customers for using mailboxes they had already paid for.

06
New mailboxes ramp up first
A campaign's volume ramp starts at 3 emails per mailbox on sending day 1 and adds 1 each sending day up to 15, so full volume comes on the 13th sending day. It is switched on by default for projects with no mailbox yet or a mailbox under 14 days of warmup. The monthly figures above are for established mailboxes, not a first month.

07
The ramp can only tighten the limit
The cap used is the smaller of the mailbox's daily limit and the ramp cap. The ramp never lets a mailbox send more than its own limit.
Warmerly product, checked 19 October 2026
08
Raising the limit is possible
The daily limit is a setting per mailbox, so a higher figure raises the ceiling. We do not publish a maximum, and sending harder from one mailbox is a deliverability risk.

How Smartlead does it
Smartlead, in detail.
Plans are priced on emails a month. Each email sent, including follow-ups and replies, uses one email credit. Every mailbox also has its own messages per day setting.
01
6,000 emails on Base
Base lists 6,000 email sends a month at $39, Pro 90,000, Unlimited Smart 150,000 and Unlimited Prime 500,000.

What counts as an email
The FAQ says an email credit is each individual email sent across any campaign. Help article 392 adds that follow-ups and replies count too.

03
Resets each month
Email credits reset with your billing cycle. Article 157 says they renew on the date of your monthly billing cycle.

04
At the limit
Help article 392 says that when email credits run out, new emails will not send until the next monthly reset or you upgrade.

05
Separate from contacts
The FAQ says Base's 2,000 contacts and 6,000 sends a month are separate counters.

06
A daily limit on every mailbox
Help article 58 says each mailbox has a Messages per day setting in its general settings, and recommends 40 to 50, counting cold emails and warm-ups together. We found no stated upper bound for the setting.

07
Max new leads per day leaves out follow-ups
Article 58 says the campaign setting Max new leads sent per day counts only leads receiving their first email, so a day's total can be higher than that figure.

08
Unlimited email accounts
The pricing FAQ says all plans include unlimited email accounts, so the monthly credit count, not the mailbox count, is the plan's volume limit.

09
Its own data on pace
Smartlead's benchmark page says the median mailbox sends 14 cold emails a day, half send between 8 and 24, and it advises keeping each mailbox at 50 cold emails a day or fewer. It also gives an average of 8 days of warm-up before cold sending.

What Smartlead does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- Whether unused email credits roll over: the help articles do not say.
- A hard upper bound for the Messages per day setting: not found. The 40 to 50 figure is a recommendation, and the benchmark's 50 is guidance, not a rule it enforces.
- Whether warm-up emails use email credits: not stated.
- Whether the free trial has its own email cap: not stated.

| Same volume as a daily average | 150 a day at most (5 x 30) | 200 a day (6,000 over 30 days, our arithmetic) |
| Mailboxes on the starting plan | 5 (Starter) | Unlimited email accounts on every plan |
| What happens at the limit | Mailbox daily limit stops that mailbox for the day | New emails will not send until reset or upgrade |
| Does a follow-up count | Not metered | Yes, each email sent is one credit |
| Resets | No send meter to reset | With the monthly billing cycle |
| Contacts held at once, starting plan | 5,000 active prospects (Starter) | 2,000 stored contacts (Base) |
| Contacts reached by a 3 step sequence | About 1,500 on 4,500 sends (our arithmetic) | 2,000 on 6,000 credits (our arithmetic) |
| Day the starting plan runs out at 300 a day | No meter; held to 150 a day, about 4,500 in 30 days | Day 20 (6,000 over 300 a day, our arithmetic) |

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Above about 150 a day, Smartlead's starting plan sends more
Our reading: above about 150 a day, Base sends more in a month than the 4,500 a Starter fleet reaches at the default limit, until its 6,000 allowance runs out at 200 a day. The default is a default, though, and you can change it.
Below about 150 a day they behave alike
Our reading: a team sending 100 a day uses 3,000 of Smartlead's 6,000 and sits inside Warmerly's 150 a day ceiling. Neither product gets in the way.
One meter, or a limit on each mailbox
Our reading: Warmerly's volume follows how many mailboxes you have, so you never get a surprise stop mid-month on a counter. Smartlead's counter is a clear number, which some people prefer, and it also lets you add mailboxes without a plan change.
Follow-ups use credits on Smartlead
Our reading: a three-step sequence uses three credits per contact, so 6,000 emails reaches about 2,000 contacts, the same figure as Base's contact limit.
Do not read no cap as unlimited
Our reading: Warmerly has no meter, but 30 a day per mailbox is a real ceiling and the ramp can lower it. A new mailbox starts at 3 a day.
Both vendors advise gentle pacing
Our reading: Smartlead's own data has the median mailbox at 14 a day and its guidance at 50 or fewer, so most senders sit well under either product's ceiling.

Smartlead
Smartlead is the better fit if

- You want to see usage as one number in Settings.
- You are comfortable with the stop-at-limit rule.
Questions
How many emails does Smartlead Base allow?
6,000 a month. Each email sent is one credit, and new emails will not send until the reset or an upgrade.
Does Warmerly cap emails per month?
Not on paid plans. Each mailbox has a daily limit, 30 by default, which is about 4,500 a month on Starter's 5 mailboxes, by our arithmetic.
Which sends more on the starting plan?
Above about 150 emails a day Smartlead Base sends more, until it uses its 6,000 at 200 a day. At or below 150 a day the two behave much the same.
What daily limit should I set?
Smartlead suggests 40 to 50 messages a day including warm-ups. Warmerly defaults to 30 campaign sends a day.
