Email scheduling

Many email warm-up tools and Mailreach.co alternatives offer a convenient automated email warm-up service. However, some companies want greater control over the warm-up process and the ability to fine-tune sending and engagement.

Fortunately, both Mailreach.co and ZeroBounce offer this capability.

ZeroBounce Logo

ZeroBounce offers two methods for warmup: self-management and the ZeroBounce-managed method. With the former method, you’ll receive a list of privately owned seed email addresses, which you can paste into the “to” field for your warm-up email campaigns. You can then schedule and send those emails at your preferred time.

Maireach.co

Autopilot (Mailreach.co’s automated option) is enabled by default. However, you can simply hit a toggle to disable Autopilot mode at any time to take manual control over the email warm-up process.

Mailreach vs. ZeroBounce email warmupⓘ reporting features

In terms of reporting, Mailreach.co and ZeroBounce are once again similar. Both reporting dashboards offer key metrics, including:

Most popular email providers will support SMTP. Examples include:

  • Reputation scores (or Inbox Scores for ZeroBounce)
  • Detailed tracking of where your emails land (Inbox, Spam, or other categories)
  • Your email warm-up and performance growth over time

If you’re warming up multiple email domains, you’ll also be able to review the listing for each to easily keep track of inbox placement/reputation scores at a glance.

warmup reporting

Finally, both platforms offer email authentication alignment tracking for SPF, DKIM, and DMARC to ensure alignment issues aren’t impacting the deliverability of your warm-up emails.

With ZeroBounce ONE™, essential email sender tools like DMARC Monitor and Blacklist Monitor are also included and are designed to synergize with Warmup for detailed email monitoring and feedback.

Does ZeroBounce have access to read my emails?

Any email warmupⓘ service will read the emails sent to the privately-owned seed email addresses, so that they can perform realistic, authentic behaviors.

However, ZeroBounce doesn’t read any emails found in the connected inbox. The company maintains strict adherence to security and privacy regulations to protect your data.

Security & compliance

Your business’s security and privacy is paramount. If you trust a service with your data, you need to know which accreditations, practices, and protocols are in place to secure your account.

ZeroBounce uses military-grade security and encryption. Specifically for Warmup, your emails will only be sent and shared with a list of seed email accounts owned and used by ZeroBounce. Your data is never exposed to another user.

Use case scenarios

Sales and cold outreach

Email warm-up is a boon for sales and outreach emails in various ways.

First, it’s common that sales professionals aren’t always up-to-date on the best email marketing practices, nor are they verifying all those new leads. These actions can cause bounce rates and spam complaints to rise, both of which hurt your email deliverability and sender reputation.

Email warm-up can counteract the damage caused by these actions, while you work with your entire team to get everyone on board with better sending behaviors.

Warm up new email domains

Businesses may need a new email domain for a variety of reasons. Whether you’re a fresh startup, looking to start over with a new domain, or setting up various subdomains, you can’t just start sending mass emails. Otherwise, they’re going straight to spam.

Instead, you need to warm up those new domains gradually and get them ready for prime time.

After 1-3 months of gradual ramp-up, you’ll then be able to use those new domains and sub-domains for more effective email outreach.

Recover from email deliverability problems

You’ve used email validation on your list. You tried new campaigns and new subject lines. Nothing seems to work, and your emails are still going to spam.

A variety of factors can cause low email deliverability scores, including domain age, history, past behaviors, email blacklists, and more. But, you can slowly reverse some of the damage by gradually warming up your domain, earning positive engagement, and winning back the trust of internet service providers.

If you’re stuck with your email marketing and need a deliverability boost, a warm-up solution is the way to go.

Frequently asked questions

Mailreach.co warms up your inboxes by sending emails from your account to a network of users. Upon receipt of those emails, they will then engage with them via opens, marking them as important and marking them as “not Spam.” As your deliverability improves, it will gradually send more emails to yield more positive engagement.
