Envoys are a special type of agent which help a country undertake certain actions. Each country has a limited number of each envoy, depending on its technology level, idea groups and other factors. It takes a certain amount of time for an envoy to complete assigned missions. There are four types of envoys: diplomats, missionaries, merchants, and colonists.

- See also: Trade#Merchants
Merchants manipulate the flow of ducats at trade nodes, where they can either transfer trade on to the next node in the route, or collect trade for their country's treasury in trade nodes other than their capital's. If collecting in their capital, they will increase the ducats collected by +10%, but are not needed to collect trade in the capital. The default number of available merchants is two.
- +3 from the trade idea group
- +1 from the expansion idea group
- +1 from the plutocracy idea group
- +1 from the East India Merchant Company event
- With the Wealth of Nations DLC, Western nations get +1 merchant for each trade company they control with the majority of the provincial trade power in a region.
- With the El Dorado DLC, Western nations get +1 merchant for each colonial nation they control with more than 10 provinces.
- See also: Colonization#Colonists
Colonists are sent to uncolonised provinces to govern and expand a colony. They can be kept in a colony in order to increase the chance of gaining extra settlers each month, but can also be recalled from a colony in progress for other missions after setting up a colony (such as setting up an additional colony, although each colony over the number of available colonists will rapidly grow in cost). The default number of available colonists is zero; unlike the other types of envoys, countries generally do not begin the game with colonists, and instead gain them by taking ideas or as part of their national ideas.
Mesoamerican religions also gain additional bonuses. Passing a Mayan, Inti, and Nahuatl religious reform allows a nation to select a Colonist as one of the five options. Selecting the Clan Migration Native idea, for nations with a Native Council government, also provides a Colonist. Parliaments also may pass a bill granting an extra colonist for 10 years.
The travel time for envoys are dependent on the distance they must travel from the player's capital, and differs between the different envoy-types:
- Diplomats perform its action instantly, then spends time travelling back.
- Missionaries are both sent and recalled instantly.
- Merchants spend time travelling both to and from the destination. A merchant can be sent directly between trade nodes without having to return to the capital.
- Colonists spend time travelling to the destination, but are recalled instantly after waiting one day.
The speed at which envoys travel are modified by the following:
- Certain Events that can trigger if the player is caught repeatedly trying to build a spy network against a nation that is friendly towards them.
