Reading: 9 minutes | First automation active: 10 minutes

Your Instagram followers belong to Instagram. When the platform changes its algorithm, your reach drops and you have no control over it. Your email list, on the other hand, is yours: no algorithm can reduce its reach, no one can take it away, and you can write to that audience whenever you want.

The classic problem was that capturing emails from Instagram required taking people outside the app: link in bio, landing page, form… too many steps, too much friction, very few emails in the end. With DM Automation by AppSorteos, all it takes is for someone to comment on your post with a keyword for the app to automatically open a private DM conversation, ask for their email, and deliver the promised resource — all without the person leaving Instagram and without you having to intervene.

This guide explains, step by step, how to set up that flow in less than ten minutes.

Why an Email Is Worth More Than a Follower

This difference is key to understanding the real value of this flow. A follower exists within Instagram: you can only contact them when the algorithm decides to show them your content, and always depending on how your post performed that day. An email gives you direct access: you can write to them whenever you want, at any time, with a message that reaches their inbox without competing with hundreds of other posts in the feed.

Key Fact: Email marketing open rates range between 20% and 40%, well above the average organic reach on Instagram, which for mid-sized accounts hovers around 5% to 10% of total followers. An email doesn’t depend on the algorithm: it always arrives.

The flow you’ll configure in this guide uses the comment as a trigger to convert that person into an email subscriber. When someone comments on your post with the keyword, the app publicly responds to the post and, at the same time, opens a private DM conversation where it asks for the email and delivers the resource instantly — without you having to intervene.

Use Cases Where This Automation Works

Before diving into the step-by-step, here are the most common scenarios where this flow delivers real results. The common factor in all of them is the same logic: you offer something of value in exchange for the email, and the delivery happens automatically.

Content Creators

Offering a free resource in exchange for the email is the most popular use case. An ebook, a PDF guide, a template, a preset pack, or a checklist: any content your audience values and that you can deliver via a link. The post announces the resource and the person comments to request it. From that point on, everything happens in the DM: the app asks for the email, validates it, and delivers access to the resource automatically. You keep the email of every interested person without having done anything manually.

If you prefer to deliver the resource without asking for the email, there’s a more direct variant: check the use case for automatic delivery of digital resources.

Businesses and Ecommerce

Sending an exclusive discount code to those who comment combines lead capture with direct sales generation. When someone comments to request the discount, they’re already showing high purchase intent. That email is worth much more than a generic follower.

Consultants and Service Providers

Capturing emails from interested people before a webinar, workshop, or service launch is a way to build a list of qualified leads. Every person who comments has already shown active interest in the topic, making them a potential attendee or client with much more potential than a cold audience.

Influencers and Communities

If you depend solely on your Instagram account and the algorithm works against you, one day you could lose access to years of work. Building your own email base from your own posts is the best way to have a direct communication channel, independent of any platform.

Strategic Tip: The key to making this flow work well is the quality of the resource you offer. The more specific and useful it is for your audience, the more people will comment. A “pack of 10 healthy recipes for the week” converts better than “a nutrition ebook.” Specificity creates desire. Desire generates comments. Comments generate emails.

The Flow Structure at a Glance

Before the step-by-step, it’s worth understanding what actions make up this flow and in what order they execute:

• Trigger: someone comments with the keyword on your post or Reel.
• Action 1 (optional): public reply to the comment, visible to everyone.
• Action 2: email request via DM, with automatic format validation.
• Action 3: final DM with access to the promised resource (text plus button with link).

Each action executes in sequence, automatically, without you having to do anything after activating the flow.

This is one of the most used flows, but it’s not the only one. You can see all the automations available in AppSorteos to combine them according to your strategy.

Step by Step: How to Configure the Flow

Step 1 — Access DM Automation and Open the Flow

There are two paths to reach the same result. You can choose whichever fits your way of working better.

Option A (recommended): use the pre-loaded template

In the DM Automation dashboard, click “Create flow” and select the template “Capture the email before delivering the content.” This template already has the complete structure ready: the comment trigger, the public reply, the email request, and the final DM. You only need to customize the texts and the link to your resource. It’s the fastest option and the one we recommend if it’s your first time.

Option B: start from scratch with a trigger

Select “Start from scratch” and choose the trigger “Comment on Post / Reel.” This opens the same editor with empty fields. From here you can add each action manually in whichever order you prefer.

Tip: The difference between the two options is speed, not result. The template comes with sample texts that serve as a starting point. If it’s your first time configuring this type of flow, start with the template.

Step 2 — Configure the Trigger: Choose the Post and Keyword

The trigger defines when and why the flow activates. In this case, it activates when someone comments on a specific post. Inside the editor, click on the “Trigger — Comment on Post / Reel” block to open it.

Choose the post:

Select “A specific post or Reel” and choose the post from the post selector. You can link one or several posts to the same flow. This is useful if you reuse the same resource across different content pieces.

Configure the keyword filter:

This step is the most important for the flow to work precisely. Choose “One or several specific words” and enter the keyword you’ll include in your post caption. Some effective examples: GUIDE, RESOURCE, DISCOUNT, LINK, PDF, TEMPLATE, INFO.

Key Fact: Short, uppercase keywords work better because they’re easy to remember and type from a phone. Avoid generic words like ‘YES’ or ‘WANT’, as they may be triggered by comments with no real intention of receiving the resource.

Step 3 — Configure the Public Reply to the Comment (Optional)

After the trigger, the flow includes the “Reply to Comment” action. This action posts a visible reply in your post’s comments, right below the person’s comment.

This action serves two functions at the same time: on one hand, it confirms to the person who commented that the process has started correctly. On the other hand, it lets everyone who sees the post know that they can also participate. That social proof effect typically generates a notable increase in the number of comments.

You can configure two or more alternative replies within this block. The system chooses them at random for each comment, making the interaction look more natural and preventing everyone from receiving exactly the same text. Some messages that work well:

“Thanks for commenting! I sent you a DM with the next step. ”

“Done! Check your direct messages. ”

If you prefer the process to be completely private with no visible replies, you can deactivate this action. In that case, the flow goes directly to requesting the email via DM.

Step 4 — Configure the ‘Request Email’ Action

This is the action that sets this flow apart from a standard automation. Before delivering the resource, the system asks the person for their email directly in the DM conversation. Click on the “Request Email” block to configure it.

Main message:

This is the text the person receives when the flow reaches this point. It should be clear, direct, and explain why you’re asking for their email. An example that works well: “Thanks for your comment! To send you the content, write your email here and I’ll send you the link instantly.”

Message if the email is not valid:

This message is sent if the person writes something that doesn’t have an email format. “That email doesn’t look valid. Please write it again.” is sufficient. You can customize it to match your brand’s tone.

Tip: validation is automatic: You don’t have to do anything extra to verify the email is correct. If someone writes ‘hello’ instead of ‘[email protected]’, the system detects it and repeats the request automatically until it gets a valid format. This ensures that all emails saved in your database are real.

Step 5 — Configure the Final DM with the Resource

The last block is the “Send DM” action. This is the message the person receives right after sharing their email, with access to the resource you promised in the post.

Message:

Be specific and direct. At this point, the person has done everything you asked: commented, provided their email, and is waiting for the content. You don’t need to sell them anything else or add extra steps. The goal of this message is just one: deliver what was promised. An example: “Done, thank you! Here’s the content I promised you. Tap the button to open it.”

Button:

Click “Add button,” write the button text (for example, “Open content,” “Download guide,” or “View resource”) and paste the URL where the resource is hosted. It can be a link to Google Drive, Dropbox, Notion, a landing page, or any accessible URL.

Tip: verify the link before activating the flow. Make sure the button link is publicly accessible before activating the flow. A private Google Drive link that requires requesting access creates a bad experience. Change the permission to ‘anyone with the link can view’ before using it here.

Step 6 — Save, Activate, and Test the Flow

Before publishing the post and activating the flow in production, run an internal test. Ask someone you trust (or use a secondary account) to comment on the post with the keyword and verify each part of the process:

1. The flow replies to the comment with the configured public message (if you left it active).
2. The email request DM arrives correctly and with the text you configured.
3. The email validates correctly when written in the proper format.
4. The error message appears if something that is not a valid email is written.
5. The final DM is sent with the button and the link works correctly.
6. The contact and email appear in the Contacts section of AppSorteos.

Once everything is verified, save the flow with the “Save” button and make sure the status appears as “Active” in the dashboard. From that moment on, the flow operates in the cloud continuously, without you needing to have the application open.

Where the Emails You Capture End Up

Every captured email is automatically saved in the “Contacts” section of AppSorteos, along with the Instagram username and the date of the interaction. You don’t have to do anything extra for this to happen.

From that section you can export the complete list in CSV format at any time. Once exported, you can use it to:

• Import it into your email marketing tool (Mailchimp, ActiveCampaign, Brevo, or others).
• Create custom audiences in Meta Ads for retargeting.
• Nurture those contacts with a welcome or sales sequence.
• Segment them by the resource they requested to personalize future sends.

If you also need to work with the data from the post’s comments (not just the emails), you can export the comments from your post directly from AppSorteos.

Key Fact: Unlike your Instagram followers, who belong to the platform, the emails you capture with this flow are yours. If Instagram changes its algorithm or your reach drops, that list is still yours and you can keep communicating with those people outside of any social network.

How to Write the Instagram Post So It Works

The automation does its part, but the post has to invite people to comment. There are three elements that determine how many comments your post will generate.

1. The Resource Has to Be Specific and Desirable

“A marketing ebook” converts much worse than “a 15-page guide with the 7 strategies I used to reach 10K followers in 90 days.” Specificity creates desire. If your resource solves a concrete problem for a concrete audience, people will want it.

2. The Keyword Has to Be Visible

Mention it more than once within the caption and do so in a way that makes it clear what the user has to do. “Comment GUIDE below” or “Write GUIDE in the comments” are direct instructions that reduce friction.

3. The Benefit Has to Be Clear Before the First Swipe

On Instagram, the caption is cut off after the first two or three lines. Make sure the resource promise is explicit in those first lines, before “see more.” If the user doesn’t understand what they’ll receive before clicking, they won’t comment.

Caption Formulas That Work

• “Comment [KEYWORD] and I’ll send you [RESOURCE] directly via DM.”
• “Want [CONCRETE BENEFIT]? Write [KEYWORD] in the comments and I’ll send it to you.”
• “This content took me [time] to create. If you want the full version, comment [KEYWORD].”
• “Only for those who comment: I’ll send you [SPECIFIC RESOURCE]. Write [KEYWORD] below.”

Ideas for Using This Flow Based on Your Business Type

Beyond the general categories, here are concrete use cases with example posts and resources to inspire you.

– If You’re a Nutritionist or Wellness Coach

Post a Reel with three eating habits and in the caption offer your complete weekly meal plan in exchange for the email. The keyword can be PLAN. The resource, a PDF with the weekly menu hosted on Google Drive. Every comment is a potential patient or client for your programs.

– If You Have an Online Fashion or Accessories Store

Post a photo of your new collection and offer an exclusive discount code to those who comment with the keyword NEW. The resource in this case is not a file, but the code itself inside the DM. The email you capture is useful for communicating future launches.

If you also want to extend the reach of that post, you can combine this flow with an Instagram giveaway to reach new audiences.

– If You’re a Designer or Photographer

Share a creative process in a Reel and offer the templates or presets you use in exchange for the email. The keyword can be PRESET or TEMPLATE. This type of resource has a high perceived value for a creative audience, which generates a very good conversion rate.

– If You Organize Webinars or Events

Post a teaser of your next event’s content and offer the registration link to those who comment with the keyword WEBINAR. The captured email helps you confirm registration and send reminders before the event.

If you also receive DM inquiries about the event, you can simultaneously activate a flow to automatically reply to all your incoming DMs and not leave any question unanswered.

Frequently Asked Questions

Can I use this flow with Reels and feed posts at the same time?

Yes. You can link the same flow to multiple posts or Reels at the same time from the post selector. This is useful if you have several active posts with the same keyword.

Is the email saved even if the person doesn’t open the final DM?

Yes. The email is registered the moment the person writes it in the DM conversation, regardless of whether they later open the resource link. What you define as successful is the captured email, not the link opening.

What happens if someone comments multiple times with the same keyword?

The flow is configured to activate once per user within a given period, which prevents the same person from receiving the same message multiple times. If that person comments with a different keyword that has its own active flow, that one will activate independently.

Can I connect this flow directly with Mailchimp or another email tool?

In the current version, captured emails are saved in the Contacts section of AppSorteos, from where you can export them in CSV. Direct integration with email marketing platforms is in development.

Is it safe for my Instagram account?

Yes. AppSorteos operates exclusively through the official Meta Business API. It does not simulate human behavior or use methods that put your account at risk.

Can I combine this flow with the follower acquisition one?

Yes. You can add the “Request Follow” action before the “Request Email” action if you want the person to follow you before receiving the resource. Check the guide on how to gain followers with Instagram automations to see how to configure that action within the same flow.

Your Turn!

You now have everything you need to activate this flow. Go to AppSorteos, choose between using the template or starting from the comment trigger, configure the messages with your brand’s tone, and launch the post with the keyword. In less than ten minutes you can have an email capture machine active that works on its own while you focus on creating content.
