Effective outreach takes time. The first and most important step is to prepare your mailbox for cold email campaigns. Your emails will not reach your prospects’ inboxes unless they are properly warmed up.

That’s why, to ensure great email deliverability, SendBuzz helps you automate the process that can help you improve your ROI.

Here is the woman who is Practicing email warm-up for doing email marketing.

Email warm-up is a way to build reputation for your new email account and increase its daily sending limit and get the ability to deliver emails to more inboxes.

When a user creates a new email inbox, they will face a sandboxing time when they will face limitations for sending a number of emails per day. For instance, Google’s famous product G Suite accounts limits email sending limits by 2000 emails/day.

So, you can start warming up your new email ID within a span of 8-12 weeks and achieve maximum deliverability by building up a good reputation.

Just like automated email warm-up, you can also try a manual email warm-up feature.

Manual vs Automated Email Warm-up

Use Sendbuzz to automatically warm up your email account without putting in any manual effort.

How to manually warm-up an email?

    • Create your email account

It’s a good practice to set up a mailbox on a separate domain to send cold emails from your brand at scale. Make certain that you select the best email provider for your mass mailing campaigns. There are tons of email providers out there including Google, Zoho, and more.

Different accounts from various providers have varying sending limits. Even though the limits of all providers should be sufficient for the warm-up process, you must plan ahead and consider the volume of your actual future email marketing campaigns.

    • Get the “from line” and signature ready

You should make your email account as professional and credible as you can by customizing the “from line” and email “signature”. Typically, you would include information in your signature that would assist your prospects in verifying who you are on social media sites such as LinkedIn or Twitter.

However, for the warm-up period, create a simple signature with no photo or links. That way, you can be certain that your signature will not interfere with delivery.

    • Configure your SPF and DKIM records

Your emails will not reach the prospect’s inbox unless SPF and DKIM records are correctly configured within the inbox. SPF simply means Sender Authentication Record. It informs your recipient’s server that you are authorized to send them email from your domain and are not being impersonated.

DKIM functions a bit differently but serves the same purpose to users. It is just another way to confirm to the recipients that you’re the one sending the message.

    • Hand-deliver a couple of emails per day

The actual warming up process begins now. Please keep in mind that this only applies to newly created email accounts on domains that have already been warmed up. The domain warm-up process is different and takes a little longer if you have a new domain.

However, if your domain is already warmed up, it is sufficient to write to contacts you already know in the first few weeks (e.g. friends or colleagues). Send them some personal messages before you begin automating.

Begin with a few emails per day and gradually increase the number. At this time, no cold emails are permitted! Only personalized and human-like messages with genuine communication and questions will elicit responses from your recipients.

You should also gather a list of addresses from various hosts, such as Gmail. That is how your new email address will gain legitimacy in the eyes of various email providers.

    • Gather a few responses and respond

The primary goal is to engage in a few casual conversations before launching automated cold email campaigns using your new email address. In addition to your friends and teammates writing back to you, you can respond by sending an email from one of your other addresses.

Pros and Cons of Using Manual Email Warm-up

When you do the manual warm-up process, you will be able to establish authority as algorithms will be able to see and predict that you are a human.


There are two major issues with warming-up emails the manual way. You will need to invest a lot of time and energy behind it. Plus, it requires a lot of maintenance as you need to deal with a huge volume of email communications between two IDs.

An example of an automated email warm-up

Selecting the automated option for email warm-up does not allow you to skip any steps.
You should still set up your email account on a separate domain (and keep the domain warm-up in mind), as well as take care of the SPF and DKIM records.

The process of sending emails to gain a good reputation is something you can automate.
You can accomplish this by using tools that send messages to and from your email account. The emails will have unique generated content and will mimic human behavior to give email providers the impression that you are manually sending them.
