Implement these tips to make
your email channel reliable!
- 1
Share email provider
Avoid using AWS SES and Mailgun for cold emailing, as they are designed for opt-in emails. Instead, consider using Google, Microsoft, or Zoho

Rotate inboxes & Use several domains
To increase sending limits, utilize multiple inboxes by setting up 4-5 inboxes per domain and leveraging an unlimited number of domains. It’s essential to regularly refresh domains that exhibit low performance to maintain optimal efficiency. We have created a mailbox calculator that allows you to determine the number of mailboxes and domains needed for your sending requirements

Email authentication
Ensure that your SPF/DKIM/DMARC is in place. These digital signatures confirm that you had permission to send the email. Without them, the receiving server may assume you are a fraud

Warm-up mailboxes
Warm up your email campaign for 2 weeks with Warmy, which automatically adjusts the number of warm-up emails and determines the optimal reply rate. After this initial phase, aim for a steady increase in the number of emails per day, while Warmy’s AI engine continues to set the ideal reply rate each day throughout your campaign

Boost email deliverability
To maintain high deliverability, avoid sending emails to your ‘Do Not Contact’ list, as being reported as spam can damage your reputation. Maintain consistent sending patterns by gradually increasing and decreasing your email volume, and always use email validation tools to check your recipient lists and keep your database clean. Prioritize aiming for a reply rather than a click. Respond to all unsubscribe requests to confirm that you will no longer contact them

Personalisation & Unique content
Unique emails are more likely to be delivered, and personalization can positively impact open and reply rates, thereby enhancing deliverability. Equally important is your subject line, as it’s the first thing recipients see and significantly influences open rates. Utilize Spintax to make each email unique and conduct A/B testing to optimize performance

Use plain text
Plain text emails generally have a higher delivery rate compared to HTML emails. However, even when composing in a standard email editor, the email will still be sent as HTML. To improve delivery rates, try to use more text rather than excessive HTML in your emails

SPAM words
Refrain from using spam-triggering words whenever possible, and review each email before adding it to your sequence. For assistance, check out our Free Template Checker

Managing email content for optimal deliverability
Minimize the use of images, including in your email signature, and consider adding them only in your second or third email if necessary. Unsubscribe links can lower deliverability rates but, on the other hand, are mandatory for bulk senders. They help reduce the risk of your emails being marked as spam. Additionally, limit the use of links to one per email, including those in signature

Email sending limits & Consistency
If you are sending from an inbox, limit your daily emails to 50-100 and distribute them evenly throughout the day. Maintain consistent sending patterns by gradually increasing and decreasing your email volume
