Hashtag suggestions from your caption, saved as reusable bags of tags
RecurPost suggests hashtags while you write a post and saves your tag sets so you never have to retype them. The feature works inside the composer when you type a caption. It pulls tag ideas from it and drops a saved group into any post with one click. For an agency running many client accounts, that removes a repetitive daily task.
No credit card required.
RecurPost suggests hashtags from your caption
RecurPost reads the caption you already typed and proposes hashtags that match it. Click the # icon below the editor, then open the Suggestions tab. RecurPost lists caption-relevant tags, and you can add the ones you want with a click.
A freelancer writing a caption for a cafe client gets tag ideas straight from the caption itself. They stay in the composer instead of opening a separate research tab.
Hashtag Suggestions suits social media managers who want relevant tags fast without leaving the post.
Hashtag Suggestions is one step inside the post composer in RecurPost, the social media management software, where you write, customize, and schedule each post. Adding tags from a caption takes 4 steps:
Type your caption
Write the post the way you normally would.
Click the # icon below the editor
The hashtag panel opens without leaving the post.
Open the Suggestions tab
RecurPost lists tags that match the words in your caption.
Add tags with a click
Each tag you pick drops straight into the post.
It does not replace hashtag volume research. RecurPost builds suggestions from your caption, not from search-volume data.
Save hashtag sets as Bags of Tags and reuse them in one click
RecurPost saves your hashtag groups as Bags of Tags. You build a set once, name it, and insert the whole group into any post with a single click. Each bag stays available across every post and every social account you manage.
An agency keeps one bag per client. The dental practice has its set. The realtor has another. The manager drops the right bag into each post instead of typing 20 tags from memory.
RecurPost lets you rename or delete a bag whenever a client’s tags change.
Bags of Tags is most suited for repeated posting of the same brands or themes; for a single post that you publish just once, typing a few tags by hand is faster.
Hashtag limits and recommended ranges by platform
Each network handles hashtags differently. RecurPost’s per-platform hashtag generators carry the researched limit for all ten social networks RecurPost supports; the five below are the ones agencies compose for most often, with each figure labelled as a platform limit, RecurPost behavior, or recommended range.
Platform limit: 5 per post or Reel in the Instagram app (since December 2025). RecurPost: publishes through Instagram’s API, which accepts up to 30. Recommended: 3 to 5.
Platform limit: none published. Recommended: 3 to 5.
Platform limit: none published. Recommended: 1 to 3.
Platform limit: none published. Recommended: no more than 2, per X’s own guidance.
Platform limit: none published. Recommended: 3 to 5.
Only Instagram enforces a hard hashtag cap, and it applies in the Instagram app; LinkedIn, Facebook, X, and Pinterest publish none, so their figures are working ranges. RecurPost pairs those counts with bags, so you can keep a 5-tag Instagram bag and a separate LinkedIn bag for the same campaign.
Each platform also sets its own character and hashtag rules. RecurPost checks every post against more than 850 known platform errors before it goes out, so a post that breaks a tag or character rule gets flagged instead of failing quietly.
How agencies manage hashtag sets across client accounts
RecurPost lets an agency store a separate set of hashtags for every client. Each Bag of Tags holds that client’s approved tags, so any team member composing for the account inserts the right set.
A 15-client agency keeps 15 bags. When a new coordinator joins, they pick the client’s bag instead of guessing which tags are on-brand.
RecurPost keeps tags consistent across a client’s posts and platforms without a shared spreadsheet.
Per-client bags help teams managing many brands at once. A solo creator posting for one account gets less out of keeping many bags.
RecurPost’s Agency and Enterprise plans carry the higher social-account allowances, so an agency can keep one bag per client account as the roster grows.
Add hashtags in the caption or the first comment
RecurPost lets you add hashtags in the caption as well as in the first comment. Instagram managers often move tags into the first comment to keep the caption clean. RecurPost drafts captions with its AI tools in the same composer, so you write the post and pull tags in one place.
