A lift in your reply rates can have a significant impact on your client acquisition, client engagement, and retention.
However, personalizing your emails takes time if you write every single one out by hand. That's where mail merge software comes in.
Mail merge software helps you personalize your emails on an individual basis but at scale. Every email you send is perfectly personalized for every individual recipient.
In this guide, we'll show you some of the best mail merge tools out there and look at some of the features to look out for when choosing the right one for your business.
Let's dive in.
What is Mail Merge Software?
Mail merge is the name given to software that automatically replaces fields like names and company names with data from a spreadsheet or prospect list you have. Merge tags are also referred to as attributes.
Here’s an example of using a mail merge, or an attribute, in practice:
Imagine you have a spreadsheet containing 100 people's first names and company names.
In your email, you insert a piece of text such as {{prospect.first_name}}.
When you send your email, the copy will automatically update to replace {{prospect.first_name}} with the person's name from your spreadsheet column.
The result is that your emails are always 100% personalized to the recipient, making mail merge and attributes a powerful tool for cold email and client engagement.

Best Mail Merge Software to Send Personalized Emails on Autopilot
1. QuickMail
Send personalized email campaigns to multiple recipients and automatically follow-up to start more conversations with qualified prospects.
Send Personalized Emails to Every Prospect using Attributes
QuickMail lets you personalize your outreach emails with ease.
If you have an existing prospect list in Google Sheets you can upload them to QuickMail with the native Google Sheets integration. If you have a CSV, you'll be prompted to map each column in the list to an attribute during the import process.
Here, you’ll confirm that each column in your spreadsheet maps to the attribute you want.
When you write your email templates, these attributes can be included, and the data will be automatically pulled in from the corresponding column in your spreadsheet.
You can include these in the email body, as well as your email subject line to ensure every recipient sees that you’re specifically reaching out to them.
You can send a template like this to multiple prospects at once, and each will receive an individual email that includes their own first name, the city they're in, their company name, and more.
The easier it is to personalize your emails, the faster you can scale up your cold email activity.
Automate the Entire Outreach Process
QuickMail helps you automate the outreach process to prospective clients. You can create multi-step and multi-channel email campaigns, with delays in between each step.
First, you’ll create the first step in your email campaign. Then, add a delay, and write your next email in the sequence.
If someone doesn't reply to your first email, QuickMail will move them onto the next step and they'll be followed up with.
Our data shows that over half of replies come from a follow-up, so it's vital to always include at least one.
You can add as many steps to an email campaign as you need.
It's an excellent way to ensure your emails always get seen by the busy decision-makers you're reaching out to.
Bring Your Team to Help Manage Campaigns
As you send more emails, the workload increases. QuickMail allows you to bring your team at no extra cost. You can collaborate on tasks, manage replies in a shared opportunities inbox, and get an overview of performance.
Each plan comes with a generous allowance of inboxes (emails for sending) so collaboration is a standard feature.
The inbox rotation feature means you can rotate your sending volume across different inboxes and reduce the chance of any one inbox being caught by a spam filter.
Native Integration With Deliverability Tools to Ensure Every Email Lands in the Inbox
Your emails need to land in the inbox if you want your prospects to read them and reply.
QuickMail has native integration with an email warm-up tool, MailFlow, which is designed to improve your deliverability.
It’s free to use, and it ensures that ESPs like Gmail and Outlook see you as a trustworthy sender.
Once you connect your inbox to the MailFlow Auto Warmer, it will send emails to and from your account, engaging with other real inboxes in our network. Your emails are then opened and replied to.
These positive engagement signals will show ESPs that they should deliver your emails to the primary inbox, and you'll rarely end up in the spam folder.
You can track your deliverability in the MailFlow Auto Warmer Report, and it works with Gmail and Outlook inboxes, as well as custom email providers.
The best part? You can get started risk-free. QuickMail offers a free 14-day trial so you can take the platform for a test drive. You’ll also get access to QuickMail’s amazing support to guide you through the setup process.
Once you’re seeing results and ready to scale up, you can upgrade to get extra tools to help you personalize and automate your mail merge outreach at scale.

Benefits of Using Mail Merge Software
There are a few good reasons to use mail merge software.
1. Improved Response Rates to Emails
Personalized emails get more responses than generic ones.
Without a dedicated tool, sending cold outreach to potential clients at scale means you need to write hundreds of emails manually. With mail merge software you can automate the email writing process, without compromising on the level of personalization in your emails.
Every recipient will see that you've put effort into researching them before reaching out, and you'll boost your reply rate.
It’ll also free you up to focus on your higher-level email strategy, rather than spending all day writing out emails.
2. Get More Done with Increased Productivity
Sending tens or hundreds of personalized emails over the course of a week is a time-consuming task.
Mail merge software can improve your email productivity by allowing you to send multiple unique emails at once to different recipients and still have each one personalized.
Most mail merge software also comes with automatic email follow-ups. If a prospect doesn't reply, you can automatically send another email to them without needing to check your inbox.
Features to Look for In Mail Merge Software
Depending on your needs, you'll care about different features in a mail merge tool. They all have different specialized features so it's always worth testing them out before you commit. However, here are some essentials to look for:
Spreadsheet upload and integrations: Because mail merge tools work by pulling in data from your prospect list, you need a tool that makes it easy to manage how you import data. Look for tools with native Google Sheets integrations, or, that make it simple to upload a CSV file.
Automatic follow-ups: Sending a personalized email to a sales prospect won't always get a response. Look for email merge software that lets you automate your follow-up emails, which will remove more manual work for you, and increase your chances of a reply.
Works with your inbox provider: Compatibility is important, and most mail merge software is designed to work exclusively with Gmail rather than Microsoft Outlook. Always verify that the tool you use works with the major email service providers, in case you need to migrate in the future.
Integrations: Your inbox connects every part of your business. The best mail merge tools will integrate with other tools, like your CRM, Zapier, and email deliverability tools.
Depending on your needs, there may be other features you need, but these are a good starting point.
Going Beyond Basic Mail Merge Fields to Skyrocket Replies
In the past, cold email outreach could see results by solely including someone’s first name in your mail merge template.
Today, the bar is higher.
Your recipients expect you to do in-depth research and reach out with an offer that’s specifically tailored to their needs.
One of the most powerful ways you can prove you’ve researched them is by including a custom icebreaker in your mail merge field.
For example, let’s say you run a company that recently opened a new office in Los Angeles. You receive a cold email saying: “Saw you opened a new office in [postcode] - recommend trying the tacos from [restaurant name]!”.
The first thing you would think is “wow - they’ve done their research”.
In your prospect spreadsheet, add a new column for this opening line and write out a custom introduction for every prospect.
There are no shortcuts to this. You can try using an AI email assistant, but even they can have flaws, so you’ll need to manually verify each opening line.
As soon as your recipient opens your email, they’ll see that you’re different from the other sales reps reaching out to them. If they receive five other emails and you’re the one that stands out, you’ll get a response.
If you need more tips on writing opening lines, check out our guide and examples here.
