Write Better Emails with AI

You want your emails to stand out and get replies. AI can help you, but you need to use it well. Let’s look at the steps to get the best results from ai email writing.

Crafting Effective Prompts

Prompts are what you tell your ai email assistant. If you want a good email draft, you need to give clear prompts. Prompts are the first step for ai-powered writing. Better prompts mean better emails.

Here’s how to make a great ai email prompt:

  1. Give simple and clear instructions. Tell the AI what you want the email to do.

  2. Add details. Say who you are, who the email is for, and why you are writing.

  3. Use a friendly tone. This helps the AI sound more like you.

  4. Ask for tone and style tips if you want your email to match your brand.

  5. Keep prompts short but include all the key facts.

  6. Try ready-made ai email prompts from Mails.ai to save time.

Tip: If the first draft is not right, change your prompt and try again. You can always change your instructions to get closer to what you want.

Here’s a quick example:

Write an email to a marketing manager at a SaaS company. Say I am a sales rep from Mails.ai. Offer a free trial. Use a friendly tone and keep it under 100 words.

When you make a good ai email prompt, the AI can write what you need. You can also ask for personal replies or ask the AI to focus on being clear and helpful.

Let’s see how AI emails compare to ones written by people:

Personalizing and Refining AI Outputs

Personalization helps your emails stand out. When you personalize, you show you care about the reader. Mails.ai lets you personalize with merge fields, spintax, and dynamic content. You can change the subject line, greeting, and even the offer.

Here’s how to personalize and improve your AI emails:

  • Use merge fields like {first_name} or {company} to add personal info.

  • Try spintax to make different versions of your emails. For example:
    {Hi|Hello|Hey} {first_name},

  • Check the AI’s writing for clarity and make sure it sounds like your brand.

  • Edit the email to remove extra words and keep it simple.

  • Add a clear call-to-action so the reader knows what to do next.

Note: Spintax lets you make many different emails from one template. This keeps your emails out of spam and helps more people see them. It also saves time and lets you test which version works best.

Personalization works well. AI-powered personalization can raise open rates by up to 26% and click rates by up to 41%. Personalized subject lines can boost replies by over 30%. If you use smart send times, you can see up to a 142% jump in replies. Some AI campaigns have open rates as high as 90% and reply rates up to 35%.

You can use these tools in Mails.ai to get better results with your emails.

Optimizing Subject Lines and Calls-to-Action

The subject line is the first thing people see. If you want them to open your email, you need a subject line that grabs them. AI can help you test different subject lines and pick the best one. You can also ask AI for tone and style tips for your subject lines.

Good calls-to-action (CTAs) tell your reader what to do next. A good CTA is clear, short, and easy to follow. You can ask the AI to write an email with a CTA that matches your goal, like “Book a call” or “Try for free.”

Here’s a chart that shows how much better your emails can do with good subject lines and CTAs:

Tip: Always check and edit your AI emails before you send them. Make sure they are clear, sound like your brand, and are short and direct. You want your emails to sound like you, not a robot.

If you use these steps, you can write emails that get opened, read, and answered. AI gives you the tools, but you make the final choices. With Mails.ai, you can write better emails, personalize them, and improve every part of your email writing.

Bulk Outreach and Inbox Rotation

The platform uses inbox rotation to spread your emails across many inboxes. This keeps your sender reputation strong and helps you avoid blocks or spam complaints.

  • Inbox rotation spreads emails over different accounts, so no single inbox gets overloaded.

  • It helps you avoid sending limits from providers.

  • Your emails look more natural to email services, which means better inbox placement.

  • The system warms up each inbox and keeps your domain healthy.

Automated Follow-Ups and Sequences

You do not want to stop after sending just one email. Automated follow-up sequences help you get more replies and keep conversations going. Mails.ai lets you set up these sequences so you never miss a chance to connect.

Follow-up Strategy

When you write an email, you can add questions or polls to boost responses. Emails with 1 to 3 questions get 50% more replies. Polls can raise response rates by up to 25%. Smart follow-ups help you build relationships and close deals faster.

Deliverability and Email Verification

You want your emails to land in the inbox, not the spam folder. Mails.ai uses built-in email verification to check your list before you send. This step cuts bounce rates by up to 50% and can lift deliverability by 25%. The AI checks for fake or outdated addresses and removes them. This keeps your list clean and protects your sender reputation.

  • Regularly verify your list to remove bad addresses.

  • Take out hard bounces right away to avoid problems.

  • Watch for soft bounces and adjust your sending if needed.

  • Use verification tools to keep your list healthy.

With these tools, you can write an email, send it to thousands, and trust that your message will reach real people. This is the key to effective message delivery at scale.
