1. How it works

Daily Limit is the maximum number of opening emails (or steps) that can be sent out (or create) within 24 hours using one slot. This is useful to manage your campaign flow and deliverability and keeps it under control.

This limit only applies to the opening steps, not the follow-ups. Sending individual emails in the cadence may overlap, and the follow-ups are prioritized in that case.

You can set this number while creating an opening email in your campaign – by clicking on the gear icon in the top right corner of the edit page. Depending on your Add-on, you’ll be able to set it up to 50, 200 prospects or even go higher than that with the Unlimited Daily Sending add-on.

Note: This limit is applied for each slot, which means that if you are running multiple campaigns using one email address, your Daily Sending Limit will be divided into them.


2. How to increase it

If you feel like your limit is not enough to fulfil your campaign goals feel free to increase it using our add-ons. Besides our basic limit, which is 50, you can purchase a daily limit of 200 or even go unlimited. Learn more about purchasing add-ons here »

Once you activate it you can change the number of daily limits in the campaign edit mode.

Remember that even with unlimited opening emails you must keep in mind your email providers limits » in order not to get blocked by them.


Note: if you want to raise this cap above 500, please contact us at [email protected]


FAQ

Q: Is this limit applied per campaign?

This limit is applied per slot, which means that you can send as many emails as your add-on allows you via one email address connected to your slot. This means that if you happen to have one prospect in two campaigns our system will count it as two separate opening emails.

Q: Is this limit also applied for follow-ups?

No, this limit only applies to opening emails. Follow-ups are only limited both by your email providers’ servers’ limits and the general limits of an email account in Woodpecker.

Q: Is the Daily Limit a set number or I can set the value by myself?

Our Daily Limit is the maximum number of prospects that can receive an opening message. You can change this number to anything that will fit you best, as long as it will stay under your Daily Sending add-on limits.

Q: I don’t need Unlimited Daily Sending – can I remove this add-on?

Yes, you can remove it by purchasing another Daily Limit, with a limit of either 50 or 200. Then your currently active limit will be automatically removed.

How it works

There are three main “switches” in the App that will help you to increase your daily email volume and better control sending:

Important: When increasing sending in Woodpecker, you need to be considerate of the limits in your email account that you connect to the app. Email Service Providers (ESPs, for short) have placed specific daily/hourly limits on their email accounts. Woodpecker needs to follow these rules just as you would.

For example, a free Gmail account has a daily limit of 500 messages, while G Suite accounts allow sending 2000 messages per day. It’s often the case that hourly limits also apply, which means you cannot send all of those 2000 messages in just an hour or two. Hitting these limits might get you temporarily blocked from sending from your ESP’s side. Learn more about these limits in this article: Sending limits of various Email Service Providers »


Daily limit (Campaign)

The daily limit controls how many opening emails at most will be sent in the campaign each day. You can set it in the campaign editing view, on the right-side panel, next to Email 1. This limit can be changed by purchasing one of the following add-ons: Daily Limit of 50, 200, or unlimited prospects contacted per day.

boost-sending-woodpecker image

Daily limit of 50 prospects contacted each day is set on all your slots by default. If you need to send more email, check our Marketplace »

If not used to its maximum, the daily limit won’t be cumulative for the next day or so. This is the highest amount of opening email which you can send in a 24h period. This setting merely limits sending and does not determine the fixed amount of emails that are going to be sent each day. Send time is randomized by the app to simulate manual sending (see Sending Settings below).

The follow-ups are not limited by this setting, and each will send when it is due (each prospect has its own follow-up schedule »).

Additionally, follow-ups may overlap in sending », if you have a large prospect base in your campaign, and set up many follow-ups in it.


Delivery time (Campaign)

Delivery time determines the daily and hourly timeframes for sending. You can set these for each email in the cadence in the campaign editing view, in the right-side panel (click to expand).

[video-to-gif output image]


Defaults & Tweaks

By default, Delivery Time is set to 24/7, i.e. 24 hours on each day of the week (including weekends). It’s a good idea to set it to your office hours. (Just don’t forget to select your time zone – otherwise, 10:00 AM might turn into midnight.)

Broad Delivery time (at least 8 hours a day) is recommended, while narrow (like 2 hours on Tuesdays) should be avoided to protect your email account from issues. Learn more in this article: What’s the Best Time to Send Email Campaign »


This setting is directly related to the hourly sending capacity that you set up in Sending settings. These two combined will give you an estimate of the daily volume of emails that are going to be sent in this campaign.

For example, with ~40 emails per hour (Sending settings), and 8 hours available for sending, 8:00 AM – 4:00 PM (Delivery Time), your campaign will be able to send around 320 emails a day (8 × 40).


Sending settings (Mailbox)

Sending settings are where you specify the general daily limit for your mailbox and set up the sending interval between your emails. That’s the ultimate switch here, so do make sure it produces the results you really need. You can tweak it in Settings → Email Accounts; click your mailbox in the list, and scroll down to find the section Sending.

boost-sending-woodpecker image


Defaults & Tweaks

The default daily limit is 500 emails, and the default sending interval is “between 90 and 140 seconds”. The minimum value for the sending interval is 10 seconds; there is no maximum value.

The daily limit can be lowered (e.g. to 500 emails per day), and the sending interval can be set to a broader range (e.g. “between 40 and 200 seconds”) to ensure maximum deliverability.


The main daily limit for your mailbox is set right here. This limit will be shared by all campaigns that are running from this mailbox on a given day. It takes precedence over the Daily limit in any campaign.

Example: If you set the main daily limit in Sending settings to 300 and have 3 campaigns running from your account, they will send some 100 emails per day each (even if the campaign-level Daily limit for each is set to 500).

The sending interval is a range in seconds, from which the App will randomly choose the time to wait before sending each next email – this is why the calculated number of emails per hour is an estimate. The smaller the interval, the more emails the App will be able to send per hour (just don’t go crazy with it).

Example: With the interval range “between 60 and 120 seconds” the first email in the campaign might be sent after 80 seconds, while the second after the next 65 seconds, third after 113, fourth after 79, etc.

This interval determines the maximum frequency of sending emails – but, on the other hand, this frequency can also be much lower, as the App always tries to send as infrequently as possible.

Example: If you have given Woodpecker 8 hours for sending on a particular day in your campaign’s Delivery Time, but only added 80 prospects to that campaign, the App will only send 10 emails per hour (80 emails will be fit to 8 hours).

Take care of the deliverability of your emails

Every email provider needs to rely on anti-spam filters that protect their network from spammers – these can be considered the “second limit” (which is never made public for security reasons). Thus, while there might be no strict limits officially, there is a list of good practices when sending large volumes of emails that help avoid having your emails classified as spam.

Bear in mind that quality cold outreach should never aim to hit these limits; while striving for “quality, not quantity”; the key to success is to send highly personalized emails. Read more »

To do pause the sending from an email address you need to go to Settings Email AccountsEdit.

Things to check first:


Separate settings for each mailbox

Each mailbox setting is separate for each email address. By default, you can send around 500 emails a day at random times, between every 90 and 140 seconds. This gives you around 30 emails per hour. Of course, you can change these numbers, having in mind your email provider’s limitations.

When you send more than one campaign from the same email address, you need to consider Sending limits and campaign settings (for example, Delivery time and sending in prospect’s timezone.)

Sending several campaigns from one mailbox

If several campaigns are set to go out from one address at the same time, the emails from all those campaigns will be sent in an interweaving way, for instance, one email in Campaign A, and another in Campaign B.

Example. You have two campaigns running at the same time from one email address: Campaign A and Campaign B. According to your default settings, you can send out around 30 emails per hour. That makes around 18 emails in each campaign: 15 messages in Campaign A and 15 messages in Campaign B, providing there were no delays or errors.

All the emails planned to be sent at the time will be put into the single queue, with the follow-ups having priority over Emails #1. Scheduled emails will be evenly distributed across all running campaigns.

What does it mean for me?

The more campaigns you have running at the same time, the longer it takes for them to complete.


Prioritizing a campaign

If you want to prioritize one of your campaigns, pause all the remaining ones to be sure the messages get into your prospects’ inboxes on time. Alternatively, adjust the Delivery time.

FAQ

Q: Over the next couple of months I plan to run a number of campaigns concurrently. Is this possible? If so, are there any limitations to this?

Yes, it is possible and there are no limitations. However, campaigns take longer to complete when you send multiple campaigns from one email address. In short, the “Sending limits” apply to one mailbox. The number of emails that you can send per hour is then distributed across all the campaigns that are running at the same time. If you wish to prioritize one campaign because you want to reach some prospects at a specific time, for example, to announce the upcoming webinar or inform about the conference, you should either pause some of the running campaigns or adjust the deliverability time.

Daily Limit

Daily Limit sets how many prospects can be enrolled in the first step of your campaign.

sending-limits-woodpecker image

The daily sending limit is the maximum number of opening emails (or steps) that can be sent out (or created) within 24 hours using one slot.

sending-limits-woodpecker image

You can change it in the campaign edit mode at any time. Just click on the gear icon in the top right corner of the page and adjust the number of prospects enrolled daily to your needs.

Remember that purchasing a higher Daily Limit add-on won’t automatically change the values in your campaign. Those need to be updated manually.


Your top limit will depend on the purchased Daily Sending Limit add-on. It can be either maximum of 50, 200, or 5500 (with Unlimited option) prospects. Learn more about purchasing add-ons here »

sending-limits-woodpecker image

This limit is applied per slot, which means that you can send (or create) as many emails (tasks) as your add-on allows you via one email address connected to your slot.

Read more about Daily Limit »

If you’ll be running several campaigns using one slot, your Daily Limit will be shared between them.


Email Account Limits

In the Email Account Settings, under the Sending section, you can find two other limits which will determine how many emails you will be able to send through your email account daily.

You can enter the Email Account Settings by clicking on the gear icon next to the email address connected to Woodpecker.

sending-limits-woodpecker image

There choose the Sending section from the menu on the left side.

sending-limits-woodpecker image

In the Sending section, you’ll find two limits: daily and hourly. The daily limit sets how many emails, including both opening emails and follow-ups, can go out in the 24h period through a connected email account.

Hourly limit tells Woodpecker how many emails our app can send in one hour. This limit is dictated by set intervals between each email sent. Keeping its value in mind when selecting sending hours for your campaign.

sending-limits-woodpecker image

You can change both of those limits by simply putting your desired numbers instead of our default ones.

FAQ

Q.: What is the maximum number of emails that I can send out from Woodpecker from one email account?

The maximum number of emails that you can send in the 24h period from the Woodpecker App is 5500.

Q.: If I run two campaigns at the same time from one email account – do they share the limits?

Yes, they will share both the Daily Limit and the overall limit of the email address connected to Woodpecker. We have an article covering the topic of Sending several campaigns from one mailbox » in more detail.

Q.: My provider’s limit is 2000 emails per day. What will happen if I send more than that?

Your provider will most likely block you from sending once you reach their limit. If you’ll do that more often, you’re risking getting blocked for a longer time and hurting your sender reputation.

Q.: What are the best limits to have?

It depends on your cold mailing goals. However, our default limits are set to secure your deliverability so you can always simply stick to them.
