Warming up your cold email addresses in tools like Instantly is crucial for ensuring deliverability and avoiding spam filters. Here’s why:

1. Builds Sender Reputation

Gradually sending emails establishes trust with email providers (Google, Outlook, etc.), proving your address isn’t a spam source.

2. Avoids Spam Flags

Sending a high volume of emails suddenly can trigger spam filters. Warming up ensures a natural increase in volume.

3. Improves Deliverability

Warming up helps your emails land in the inbox rather than the spam folder.

4. IP and Domain Health

Email providers track IP and domain activity. Warming up keeps your sending reputation clean and healthy.

5. Better Open Rates

With a higher reputation and improved deliverability, your emails are more likely to be opened.

Instantly’s warm-up process automates this by sending small, increasing amounts of emails and engaging with them (opens/replies) to simulate real user behavior.

Step 1: Sign Up or Log In to Instantly

• Go to Instantly and create an account if you don’t already have one.

• Log in to access the dashboard.

Step 2: Add Your Email Account

• In the Instantly dashboard, click on “Add Email Account”.

• Enter the email credentials (SMTP/IMAP settings if required).

• Choose the email provider (Gmail, Outlook, custom domain, etc.).

Step 3: Enable Warm-Up

• Once your email account is connected, toggle the “Enable Warm-Up” feature in the settings for that specific account.

• Instantly will now begin sending emails on your behalf to other accounts in their network for warm-up purposes.

Step 4: Configure Warm-Up Settings

• Set Daily Limits: Start with a low number of emails (e.g., 5–10/day) and gradually increase by 5–10 emails per day. This mimics organic usage.

• Set Reply Ratio: Adjust the percentage of emails that will receive replies (e.g., 30–50%).

• Schedule Timing: Spread emails throughout the day rather than sending all at once.

Step 5: Allow Instantly to Handle Engagement

• Instantly will automatically:

• Send emails to real accounts in their network.

• Open emails and reply to them.

• Remove emails from spam folders if they land there.

• This improves your sender reputation and deliverability.

Step 6: Monitor Metrics

• Go to the Warm-Up Report section in the dashboard.

• Check:

• Spam Rate: Percentage of emails landing in spam.

• Open Rate: Indicates deliverability success.

• Reputation Score: A gauge of your email account’s health.

Step 7: Avoid Manual Interference

• During the warm-up period, avoid sending manual outreach emails from the same account. This can disrupt the process and negatively impact reputation.

Step 8: Gradually Transition to Active Campaigns

• Once warm-up is complete (typically after 2–4 weeks):

• Instantly will notify you that the account is ready.

• Start active outreach campaigns, beginning with a low volume and increasing gradually.
