So you’ve decided to take your own sales team to the next level and you’re on the lookout for a cold email tool that will fit your needs perfectly and speed up your sales cycle.

The thing is, though, that there are lots of choices when it comes to the best cold email software out there, and sometimes it’s not easy to find the one that’s right for you.

I’ve made things a little easier by preparing a list of the best platforms for cold emailing. Use it to compare your options and find the right cold email software for you.

What should you look for in cold email software?

First things first – what features should a good cold emailing tool have? The best cold email outreach tools and software platforms share these features:

Deliverability

• a sending algorithm that sends emails at random time intervals, just like a person would, to spread sending times out and look more natural
• email verification to avoid bounces and protect your domain reputation
• custom tracking domains

Personalization

• custom fields to add elements that allow you to personalize your campaigns at scale

Automation

• automated follow-ups
• reply detection (which stops the sequence)
• A/B testing to optimize your cold email outreach

Integrations

With the business tools you regularly use to get your job done, like:

• HubSpot
• Salesforce
• Calendly

Woodpecker Cold Email

Deliverability

We make sure Woodpecker’s sending algorithm is geared towards ensuring the best deliverability possible. Woodpecker sends emails at random moments within a specified time frame to mimic human sending. All good cold email software platforms do this to help your messages avoid being labeled as spam emails by the email service provider used by your recipients.

The ability to verify multiple email accounts and addresses is important too. Every time Woodpecker sends an email campaign, each email address gets verified just before it’s sent. The built-in real-time email verification helps you to avoid bounces.

Without email validation, you can ruin your campaign statistics by sending messages to inboxes that are full or addresses that don’t even exist.

Woodpecker is the best platform for cold emailing since as a user you can use the warm-up add-on, which is at least 5x cheaper than other warm-up tools. It helps you build a strong email reputation and ensure that your emails end up in the primary inbox and not in the spam folder. Thanks to AI, it interacts positively with your email account with real emails and email content, making the whole process more human.

With Woodpecker you can also track your clicks safely with custom tracking domains. This can be important for your sales process and help your sales team track which leads are at which point of the funnel you have set up.

Two special features that really make our cold email tool stand out from the competition are the Deliverability Monitor and Sending Volume Monitor

Deliverability Monitor keeps track of your sending processes and deliverability trends. By using this feature, you can notice if there are any potential issues with your deliverability, and react in time to avoid them. Remember that sudden changes in deliverability can be early warnings of serious problems that can affect your email campaigns.

Sending Volume Monitor prevents potential deliverability drops by stopping you from exceeding your email’s provider sending limits. Daily limits on sent messages are assigned per user and Woodpecker automatically pauses your cold email campaigns if you come close to exceeding them. This helps to prevent your cold email outreach campaigns from getting blocked by your email provider.

Automation

Of course, all cold email marketing software allows you to automate follow-ups and create email sequences — these are core features of any cold email tool.

Woodpecker detects replies from your prospects and automatically stops email sequences when someone responds or gets in touch with you.

One of the most useful cold email marketing tools you get with Woodpecker is the ability to A/B test your messages. You can test up to five variations of a message to see which one gets the best response from your recipients.

Another automated feature is the ability to send follow-ups in the same threads as your opening message.

Personalization

You can use snippets (custom fields) to add a human touch to your messages and easily personalize your sales outreach.

To better tailor your messaging, you can set conditions based on prospect behavior, and even start your campaign with a condition. Personalized email campaigns always get better results, so these tools to enhance your cold outreach are a must when reaching out to prospects without prior contact.

You can also send emails in the prospect’s time zone. Woodpecker will automatically match the country with the timezone once your prospect’s country is included in your data.

Integrations

Woodpecker is natively integrated with all these tools and more:

• Calendly
• Pipedrive
• HubSpot
• Google Sheets
• LeadFuze
• UpLead
• Hunter
• and more

Snov.io

Deliverability

This cold emailing tool verifies your emails, but it does so in bulk. You need to import the list. This means they’re not checked in real time.

Snov.io doesn’t offer an email/domain warm-up feature, so you’d have to handle the process manually.

Automation & personalization

Snov.io offers some email automation features. It makes A/B testing available but it’s only available for users starting with an M plan. So, if you have an S plan or freemium, you won’t be able to A/B test your emails to find the best-performing version for your email campaign.

You can add conditions to your campaigns that are based on prospect behavior.

You can send personalized cold email campaigns by using custom fields.

Integrations

Snov.io is natively connected with Pipedrive. To use it with other CRMs and tools, like HubSpot, Zoho CRM, Salesforce and Asana or Airtable, you have to do it via Zapier.

Free trial & pricing

Free Trial: Snov.io offers a free trial.

Pricing: There are 6 options:

• S, for $39 per month – for startups and solo entrepreneurs. Includes 1000 credits and 5000 unique recipients.
• M, for $99 per month – for small sales and marketing teams. Includes 5000 credits and 1000 unique recipients.
• L, for $189 per month – for companies expanding their reach. Includes 20000 credits and 30000 unique recipients.

Reply.io

Deliverability

Reply.io has a warm-up feature to boost your cold outreach campaigns. You have to pay for it extra, though – $29/month per account. This cold email software validates the email addresses on your list with a built-in integration, and you can also use custom tracking domains.

Automation

Reply.io detects when someone writes back to you, and you can also A/B test your messages to see which one gets better engagement.

Personalization

This cold email tool allows you to personalize the content of your emails with variables. You can also use conditional variables to add conditions of if/else format within your email sequences.

Free trial & pricing

Free trial: You can try Reply 14 days for free.

Pricing: There are three types of plans: Sales Engagement, Email Search, and Email Warm-up.

• Sales engagement is divided into 3 user types. For businesses, the prices are $70 a month per user (starts at 3 users), $60 a month per user (starts at 5 users), or $50 a month per user (starts at 10 users).
• Email Search has three options, too: free, $49 a month with 5000 email credits a month, and $99 a month with unlimited email credits a month
• Email Warm-up – $29 a month per email account

Quickmail

Deliverability

Cold email platform Quickmail gives their users an email warm-up option. This feature is called Auto-Warmer and it’s free for up to 50 inboxes per account per user.

This cold email tool allows you to verify emails, but it costs extra – you need to buy credits every time you want to verify email addresses on your list.

Personalization & automation

If you’d like to increase your prospect engagement with email personalization, you can do it with Quickmail’s integration with Hyperise.

You can A/B test your emails with Quickmail and see which variation does a better job engaging prospects.

If you’d like to send a follow-up in the same subject line or thread as your opening message, you can’t do it with Quickmail.

Integrations

Quickmail integrates with email verification tools like DropContact, ZeroBounce, and NeverBounce, and other business software, such as Aircall, Twilio and Slack.

Free trial & pricing

Free trial: Quickmail offers a 14-day free trial.

Pricing:

• Auto-Warmer Plan is free
• Starter Plan: $59/month. You can send 500 emails a day per inbox with this plan. Everything from the free plan plus Bounce Detection, Multi touch email campaigns, auto follow-ups, Live notifications.
• Pro Plan, for $79/month. Everything from Free and Starter Plan plus Zapier integration, Conditional Steps, Auto import spreadsheets and weekly deliverability report. You can send 1500 emails/day/inbox with this plan.

Lemlist

Deliverability

Lemlist is one of many cold emailing tools that offer a warm-up feature (they call it Lemwarm). It allows you to handle the warm-up process automatically, but only in one scenario, which means the process looks the same if you’re warming up a domain and an email account.

When it comes to email verification – another crucial deliverability feature – Lemlist is integrated with Bouncer, but it’s not a built-in integration. To use it, you need to set it up using an API key and configure it on your Bouncer account, and then every time you want to verify your list, you need to do it in your Bouncer account.

Lemlist offers custom domain tracking, which helps to track clicks safely. This cold email tool lacks a way to monitor your deliverability stats, though, and it doesn’t protect you from exceeding your email provider’s sending limits.

Automation

Lemlist has a reply detection feature – when a prospect replies or clicks on a link, it will stop sending the rest of the campaign automatically.

They also allow you to A/B test your emails, which is a must for any good cold email outreach software. You can’t send follow-ups in the same thread, though.

Personalization

With Lemlist, you can use liquid syntax and spin syntax to personalize your message. You can also add text to images you attach in your email, and build a landing page.

Integrations

Lemlist is natively integrated with CRMs like Salesforce, Hubspot and Pipedrive.

Free trial and pricing

Free Trial: Lemlist offers a free 14-day trial.

Lemwarm isn’t available on the trial.

Pricing: There are three pricing plans:

• Email Warm-up – $29/month (only lemwarm);.
• Email outreach – $59/month;
• Sales engagement – $99/month/

Outreach

Outreach is a more robust platform for enterprises, and as such is on the higher end in terms of price. It might be more accurate to call it a general sales engagement platform.

Deliverability

Outreach offers many features, but a warm-up system is not one of them. This cold email tool also doesn’t verify the email addresses on your list. You can use custom email tracking domains, though (they’re called Branded URLs).

Automation

You can put prospects in an automated sequence (called a playbook).

You can A/B test your messages with Outreach and use automated follow-ups.

This same cold calling and email tool also offers products such as Outreach Kaia (an in-call transcription assistant) or Outreach Commit (which helps you with sales forecasts). If cold calls are important to you, Outreach might be worth a closer look.

Personalization

You can use snippets to personalize your emails and build message templates.

Integrations

Here are some of Outreach’s native integrations: Salesforce, Google Calendar, Linkedin Sales Navigator.

Free trial & pricing

Free Trial: Outreach.io doesn’t have a free trial.

Pricing: In order to see how much you’d have to pay, you’d need to request that info on their pricing page.

Mailshake

Deliverability

Mailshake has a warm-up system called Warm Up Your Email. When you want to use it, you need to start with setting up your daily sending volume.

This cold email tool also offers email verification – you have to buy credits to conduct it, though, and it’s done in bulk, instead of in real-time before each email goes out.

Automation & personalization

As in all the other cold emailing software options listed here, you can use custom fields to personalize your emails in Mailshake.

When someone replies, Mailshake pauses your email sequence.

A/B testing, which is also included in Mailshake, allows you to test variations of your campaign to see which variation works better.

Integrations

Mailshake is natively integrated with CRMs like Pipedrive, HubSpot, and Salesforce.

Free trial & pricing

Free trial: No free trial.

Pricing: Here’s Mailshake’s pricing:

• Email Outreach option – 59$ per month
• Sales engagement option – 99$ per month

Apollo.io

Another one of the best cold email outreach software options is Apollo, which is strongly focused on helping you with prospecting. Let’s see how it looks in terms of cold outreach email features.

Deliverability

Apollo won’t help you with your email or domain warm-up, nor with validating your email list, but they do offer custom tracking domains for safe click tracking.

Automation & personalization

Like every cold emailing platform, Apollo allows you to use custom fields for personalization. You can also A/B test your messages with the software.

Integrations

This cold email tool doesn’t have a large integration base, and to use any integrations you need Zapier.

Free trial & pricing

Free Trial: a 14-day trial, limited to 50 email credits per month.

Pricing:

• Basic plan – $49 per month. Limited to 200 email credits per month.
• Professional plan – $99 per month, unlimited email credits and 50 mobile numbers per month.
• There is also a Custom plan, where you receive everything from the Professional plan, plus some advanced options.

Klenty

Deliverability

You won’t be able to automatically warm up your emails and domains with Klenty. Also, if you want to have the email addresses on your list verified, you have to use a separate tool to do so, as this cold email tool doesn’t offer such a feature.

You can use custom tracking domains, though.

Personalization & automation

Klenty’s Liquid Templates can help you with personalizing your emails, and you can also record and add videos to your messages (if you integrate Klenty with Hippo Video).

This cold email software also allows you to use A/B testing to see which template in a running campaign gets a better response rate.

Integrations

Klenty is natively integrated with tools such as Pipedrive, Zoho CRM, Hubspot, Salesforce and Slack.

Free trial & pricing

Free trial: 14-day free trial

Pricing: There are 3 price plans:

• Start up, billed $55 monthly, includes Email Cadences, API, Zapier Integration, Gmail plugin and Mail Merge.
• Growth, billed $85 per month, includes everything from Start up plan, plus CRm integrations, video personalization, multichannel outreach and more.
• Enterprise, including all options from Growth plan, billed $145 per month, also includes Monthly customer success review, Monthly deliverability reports and IP based login restrictions.

Yesware

Yesware is an add-on for Gmail and Outlook that helps you track your emails.

Deliverability

With Yesware, you won’t be able to put your email or domain warm-up on autopilot. This cold email tool also won’t verify your email list to make sure your emails don’t bounce.

Automation & personalization

Yesware notifies you when your recipient engages with your email, so you can follow up with them.

It also offers custom email templates that might help you write messages (although using ready-made templates isn’t the best idea).

It’s not possible to A/B test your emails with this cold email software, so it might be difficult for you to see which template in your emails works best for the open rate.

Integrations

You can integrate Yesware with Salesforce and LinkedIn (which means adding LinkedIn Sales Navigator to Gmail), and several other tools.

Free trial & pricing

Free Trial: 14 day trial.

Pricing: There are four paid plan options:

• Pro Plan – $19 seat/month, includes some of the features as: Unlimited email open tracking, unlimited attachment tracking, unlimited email link tracking, personal activity report and email and phone support.
