DMFast vs LinkDM

LinkDM’s free plan is the bigger one by volume: one Instagram account, up to 1,000 DMs a month, and automations for posts, Reels, Stories and Facebook comments. Its pricing page lists access to your last 10 posts, and DMs sent on it carry LinkDM branding. The public reply under each comment, email capture and inbox automation start on Pro.

DMFast’s free plan trades volume for features. It covers one account and 100 people a month, counting each person once however many messages you swap, and includes comment-to-DM with the public reply, Story replies and mentions, DM keywords, up to 10 collected emails and a bio page. The units differ, so the numbers don’t line up one to one: LinkDM counts DMs sent, DMFast counts people.

Tip: A rough test: one Reel that draws 300 keyword comments in a month fits LinkDM’s free plan even if each person gets two messages. On DMFast the same Reel needs Pro, because Free covers 100 people.

LinkDM Pro is $19 a month, or $182 a year, for 25,000 DMs a month and up to 3 Instagram accounts. It adds the public comment reply, branding removal, Lead Gen for emails, inbox automation, reminder DMs, Rewind for older comments, replies on ads and Instagram Lives, and a slow-down mode. Platinum+ is $99 a month, or $832 a year, for 300,000 DMs a month, 10 accounts, a DM overflow queue and chat with the LinkDM team.

DMFast climbs in smaller steps: Pro at $9 for 3 accounts with unlimited people and emails, the follow check, a reminder, scheduled DMs and older comments; Growth at $14 for AI replies with 1,000 credits a month; Business at $29 for 10 accounts and 5 seats. LinkDM has nothing between $19 and $99, so an agency that outgrows 3 accounts goes straight to Platinum+. Prices were checked on 6 October 2026.

In LinkDM you link a post or Reel and choose whether a trigger keyword or every comment starts the DM. The free plan also includes Inbox Starters, which shows up to four conversation starters in your inbox, and Next Post, for drafting the automation of a post you haven’t published yet. Pro adds Universal Triggers, set once and reused across placements, plus flow automation and a DM Planner for scheduled posts.

A DMFast auto-DM needs a post or Reel, a comment word such as LINK, a public reply and an opening message, all on one form. It starts with plain text asking them to reply, and the link card arrives once they answer. On Pro you can hold the link until the person follows you and send one reminder message if they stop partway.

LinkDM names several features for this moment. Its home page describes a conservative send limit in line with Instagram’s developer guidelines and a queue so DMs aren’t missed; Pro adds a slow-down mode for Reels that are “blowing up”, and Platinum+ an overflow queue.

DMFast works to Instagram’s hourly ceiling of 750 private replies to comments per account, keeping below 700 and holding the overflow in a queue that clears within the 7-day window. It also ignores link and promo-spam comments and answers each person once a day per auto-reply, so bots don’t eat into your replies.

Tip: No tool can send a private reply to a comment more than 7 days old through Meta’s API, so LinkDM’s Rewind and DMFast’s replies to older comments both reach only the past week of comments.

• Facebook: both answer Facebook comments with a DM, and LinkDM includes it on the free plan. DMFast also answers keywords sent to your Page in Messenger. Its Story replies and follow check are Instagram-only, as Facebook has no equivalent.
• Emails: LinkDM’s Lead Gen, on Pro, captures addresses in the chat, and its home page lists connecting lead forms to Kit and Flodesk. DMFast asks for an email before the link goes out, rejects throwaway addresses and exports a CSV. If your list lives in Kit or Flodesk, LinkDM saves the import step.
• Follows: DMFast’s Pro plan can hold the link until someone follows you on Instagram. LinkDM’s Pro plan lists a “Follower Growth Tool” without describing it on its home or pricing page, so ask LinkDM how it works before relying on it.
• Track record: LinkDM says it has been a certified Meta Business Partner since 2021 and uses the official Instagram APIs. DMFast is built on Meta’s official APIs too.
