A small new feature added to {emayili}: the ability to interpolate content into the email message body.
Load Package
Load the {emayili} package and create a message skeleton.
library(emayili)
options(
# Always print message body.
envelope_details = TRUE,
# Print message from pipeline.
envelope_invisible = FALSE
)
# Create a message skeleton.
#
email <- envelope()
Body
Now let’s look at different ways to add a text body.
If you know precisely what your message is going to say, then you can just write it straight into the message body.
email %>% text("Hello Alice!")
But what if a part of the message is stored in a variable? Use the {glue} syntax for variable interpolation.
name <- "Bob"
email %>% text("Hello {name}!")
This should make generating automated (yet personalised!) emails a lot simpler. For example, here’s how you’d go about creating emails from a data frame with columns holding names and email addresses.
tribble(
~email, ~name,
"alice@google.com", "Alice",
"bob@yahoo.com", "Bob"
) %>%
pwalk(function(email, name) {
email <- envelope(to = email) %>% text("Hello {name}!")
print(email)
})
