Finding an effectively synonym is tricky because the adverb has two separate meanings. In she led the meeting effectively it means successfully or well. In the decision effectively ended the project it means in effect, virtually or essentially.
Grab a word from the other sense and your claim shifts. Writing "the new rule virtually closed the park" says the park is all but closed, while "the new rule successfully closed the park" praises the rule. Both senses get another word for effectively below, and see the effective synonyms page for the adjective.

Efficiently means without waste, not just with success. A slow, careful fix can be effective but not efficient.
Test which effectively synonym you need
Ask yourself: is the sentence praising how well something was done, or saying what something amounts to in reality? If it is praise, use the first group. If it is about the real result regardless of labels, use the second.
| Sentence | Meaning | Good swap |
|---|---|---|
| The ad reached teens effectively. | It worked | successfully |
| She manages time effectively. | She does it well | well, skillfully |
| The ban effectively ended street sales. | In reality | in effect, virtually |
| He is effectively the boss. | In practice, not by title | essentially, in all but name |
Plain to advanced: words for doing it well
The strip shows the praise sense, from plain to advanced. Well is the everyday choice and often the best. Successfully stresses a clear result. Productively suggests useful output, like a productive afternoon. Competently means to a good standard, though it can sound faint, as if nothing special happened. To good effect is the most polished and suits essays and reviews.

In effect, virtually, essentially
The second sense says what is true in practice. In effect is the closest swap. Virtually and practically mean almost completely. Essentially and basically mean at its core, with basically being casual. In all but name fits when the title is different from the reality.
A history essay: "The treaty effectively gave the region independence." If the treaty never used that word, "the treaty gave the region independence in all but name" is sharper and shows you understand the gap between label and reality.

Words to keep apart
Efficiently means with little waste of time or money. Effectually is old-fashioned and rarely needed. Actually means in fact, which is close to the second sense but used for surprise or correction, as the actually synonyms page explains. Ultimately means in the end, a time idea, not a reality idea.
Antonyms of effectively
Only the praise sense has true opposites: ineffectively, poorly, badly and unsuccessfully. Inefficiently is the opposite of efficiently, so use it only when waste is the problem. The in effect sense has no clean antonym, but in name only or on paper express the contrast.
- The rules were enforced poorly.
- He is manager on paper, but his deputy runs things.

Frequently asked questions
Is efficiently a synonym for effectively?
Not exactly. Effectively means it worked, while efficiently means it worked without wasting effort. Something can be one without the other.
Communicate effectively: what can I write instead?
Communicate clearly, explain well or get the message across all work. Clearly is usually the best swap.
Can virtually replace effectively?
Only in the in effect sense, as in the law virtually banned the practice. It cannot mean done well.
Which effectively synonym suits an essay?
To good effect works for praise, and in effect or essentially works for the in practice sense. Avoid basically in formal writing.
Effectively on a resume: should I keep it?
Usually cut it and show a result instead. Numbers prove effectiveness better than the adverb does.
What does effectively mean in a sentence like he effectively quit?
It means he did not formally resign, but his actions amounted to quitting. In effect or for all practical purposes are good swaps.
