FAQ: What Are the QuickMail Features That Can Help with My Deliverability?

QuickMail is a cold email platform designed with a strong focus on email deliverability. Its features are specifically built to help users optimize their outreach and improve their success rates.

Here are some features you can use to enhance email deliverability:

Throttle Emails

High email volume can harm deliverability. Experts recommend keeping it to around 100 emails per day. Increasing the time delay between sends also helps your activity appear less spammy. By default, QuickMail adds a delay of 60–120 seconds between sending emails.

To increase the delay and set up a daily email limit, see: Throttling Emails to Avoid Getting Flagged

Inbox Rotation

If you need to send more emails without compromising deliverability, consider adding multiple email accounts. In QuickMail, you can rotate different email accounts within the same campaign.

Reduce Bounces

Verifying leads before sending is essential to minimize bounce rates and protect your sender reputation. QuickMail provides in-app lead verification using email verification credits and also supports external email verification providers.

Warm Up Your Email Account

Warming up new email accounts is important for building sender reputation and improving deliverability. While there is no strict timeline, a warm-up period of at least two weeks is recommended.

Auto-warmer is available in QuickMail for email accounts purchased directly through QuickMail. For more details, see: QuickMail Auto-Warmer

Users can also warm up for free at Mailflow.io. Sign up at Mailflow.io and follow this guide: How does the auto-warmer work?

If you have a paid QuickMail subscription and would like to increase your daily auto-warmer limits, contact support at support@quickmail.io.

Set Up Custom Domain Tracking

Custom domain tracking allows you to use your own domain to track link clicks and opens. When leads see links with your domain's branding, the email appears more trustworthy and they are more likely to click.

Create Smart Sending Groups with Deliverability AI

Deliverability AI automatically replaces email accounts with low deliverability scores in a campaign with higher-performing ones, helping your campaigns stay effective without manual intervention.

With Smart Sending Groups, you can manage and optimize your email accounts based on performance. The feature runs daily checks to maintain high deliverability across your account.

Monitor Your Domain Health

QuickMail provides SPF and DKIM monitoring to keep your email authentication setup running smoothly, along with daily monitoring across 96 blacklists. You will receive instant notifications if any of your sending domains are blacklisted, and again when they are cleared. You can also check domain status at any time on the Domain Health page.

Use Text Variations (Spintax)

Text variations allow you to diversify the content of outgoing emails, helping prevent campaign fatigue and reducing the risk of spam filters flagging your account for sending repetitive content.

For a guide on how to use them, see: Text Variations (Spintax)

Create Multiple Email Variations

Creating multiple email variations lets you test different email copies to see which performs best, measured by opens, clicks, unsubscribes, and replies. It also makes it harder for spam filters to flag your emails for sending similar content repeatedly.

Use Liquid Syntax

Liquid syntax allows you to dynamically insert lead details such as names or custom properties into your emails, making messages more relevant and personalized. Increased personalization reduces the risk of emails being flagged as spam, improving deliverability.

Reword Email Copies with AI

Reword with AI automatically rephrases email content while keeping the original meaning intact. This helps improve deliverability by reducing the repetition of identical messages across sends.

For setup instructions, see: Reword with AI

Enable Visible Image Tracking

Gmail may flag emails that contain invisible tracking pixels, showing recipients a banner that says "Images in this message are hidden" along with a prominent "Report spam" button. This can decrease reply rates and increase spam reports.

QuickMail's Visible Image Tracking feature addresses this by allowing open tracking to be based on visible images instead of invisible pixels.

For more details, see: Visible Image Tracking

Consider the Readability Score of Your Emails

The readability score is displayed when composing emails and replies. It evaluates sentence length and word choice to help ensure your message is clear and easy to read. A higher score generally leads to better engagement.

Stealth Mode

Stealth Mode prevents Google from detecting that emails are being sent from a third-party platform, which helps improve deliverability. It is only available for email accounts purchased through QuickMail and is enabled automatically.
