SMTP & IMAP are the two main protocols that allow you to send and receive emails. Why am I even writing about this? Well, sometimes we take crucial things for granted. We use them every day and don’t ever think about how they work. I believe that this is one of such things. And I think that it’s worth understanding how sending your emails works, especially if you send a lot of them as a part of your job.
This will also allow you to understand better how email automation systems work, and how sales email automation systems, such as Woodpecker, differ from email marketing systems, like MailChimp or GetResponse. Read on to learn more about how SMTP and IMAP work for your email.

What is SMTP & IMAP?
Simple Message Transfer Protocol (SMTP) is what your email client (e.g. Gmail, Thunderbird, Outlook, etc.) uses to send your email messages to your email server. The email server is often hosted by your email service provider, for instance Google, but it can be also hosted by your Internet service provider (most often by the same one that hosts your domain).
Next, SMTP is also used by the email server to send your message to the mailbox of your recipient’s email server. From there, the recipient’s email client can fetch your message using Internet Message Access Protocol (IMAP) and put it in their inbox, where they can access it.
Why is it good to know that?
We use email every day. According to a Radicati’s report, the number of business emails sent per day in 2017 is estimated at 120.4 billion. Every day! What’s interesting, the total daily number of emails sent worldwide is estimated at 225.3 billion. That means over a half of all email messages sent daily are actually business emails.
This technology still grows despite the onset of other means of communication online, like social media, chats, video chats, live streaming, and so on. That means people keep using it, even if they start using new ways of communication.
You definitely want your emails to be smoothly sent and safely delivered to their destinations – especially if they are business emails. Once you understand the mechanisms that are used to send and receive emails, you will be able to:
- take control over the process of your email delivery,
- better understand the mechanisms that affect your email deliverability,
- improve your deliverability and the engagement of your email recipients,
- and as a result, get more replies from interested prospects.
And those are the reasons behind this post.
SMTP & email automation
If you’re using email at work, there’s a high probability that you’re also using some kind of email automation. You may be, for instance, sending marketing emails or newsletters using a marketing automation tool like MailChimp, FreshMail, or GetResponse. Or you may use sales email automation for cold email sequences, using Woodpecker or similar tools.
Now, email marketing tools and sales email automation tools differ in terms of SMTP – that is, in terms of how they actually send your emails. And I really want you to know the difference because this will allow you to understand why you should use the right type of a tool for sending a specific type of email campaigns.
How does an email marketing tool send your emails?
First of all, email marketing tools, like MailChimp, host their own SMTP servers. That means, your marketing email campaigns won’t really get sent from your regular email server. Your addressee will see your address as the sender of the message, but the email won’t be sent from your mailbox.
Secondly, because email marketing tools use many servers for sending a lot of email at once, your messages will be sent very quickly, even if there’s a lot of them scheduled to be sent.
Finally, email marketing tools, like MailChimp, were designed to send newsletters, info about promotions, and updates. That is why the messages sent by those tools will get into the Promotions or Updates folders of your receivers’ inboxes.
Plus, even if you use a drip campaign option to send some follow-ups, your prospects’ replies won’t get detected, so the following messages will be sent to them even if they respond to one of your previous emails. And that’s a real bummer.
Why not use email marketing tools to send cold emails?
If your plan is to send an email with a beautiful HTML template, promoting your new service, or encouraging people to click a link to your new landing page, and you want to send it quickly to hundreds or thousands of subscribers (people who’ve previously opted in to get info via email from you), you should go for email marketing tools like MailChimp, ConvertKit, or FreshMail.
How does Woodpecker send your emails?
In terms of SMTP, Woodpecker is more similar to an email client than to a marketing automation tool. Woodpecker will actually use your own SMTP on your regular email server to send the messages. So the emails will be actually sent from your own mailbox.
That means you won’t be able to send hundreds or thousands of messages over a very short time period. Actually, you won’t be able to send even two messages at the very same moment. Your messages will be sent one by one, and sending a campaign to 40 people will actually take at least an hour (but it may take even more, depending on your delivery time settings).
As a result, your messages will be delivered straight to the Primary tab of your prospect’s mailbox. In there, they’ll be most likely to opened, read, and responded to.
And once the prospects respond, Woodpecker will detect that and stop the automatic follow-up sequence, so that they don’t get any messages they aren’t supposed to get. That’s why sending cold email campaigns from Woodpecker, or other similar tools designed for sales email automation, is actually more effective and safer.
Can I use a sales email automation tool to send a newsletter too?
If you plan to send a cold email sequence, to people who haven’t subscribed to any of your lists and don’t know you yet, use a sales email automation tool like Woodpecker. This will allow you to get to the prospects’ primary inboxes and make sure that they don’t get any unnecessary automated follow-ups.
“Ok, so can I use Woodpecker to send my newsletters as well? I want my subscribers to notice them, open them, and engage with them!” – if you couldn’t stop this question from popping up in your mind, here’s an answer:
I wouldn’t use Woodpecker to send newsletters if I were you. First of all, I couldn’t send all of the planned marketing messages at the right time. Secondly, I couldn’t use any HTML templates to style the message. Third of all, I wouldn’t like my subsequent messages stopped from being sent in a case when someone replies to my newsletter (and that happens to me regularly).
Why is it important to understand the email sending process?
SMTP is used to send your messages. IMAP is used so you could receive them in your email client. Email is still a widely popular technology, especially in business environments – that’s why it’s important to understand how it works, at least in general.
Email marketing tools – designed to send newsletters, and sales automation tools – designed for sales email outreach, send your emails in a significantly different way. That’s why it’s crucial to use the right type of a tool for the right type of email delivery.
I hope this post clarified some of the technicalities of the email sending process, and that it will help you choose the right tools for sending various kinds of your business emails.
