Dear Shareholders:

I am pleased to announce that the Board of Trustees (the "Board") of First Trust
Exchange-Traded Fund VI (the "Trust"), on behalf of International Multi-Asset
Diversified Income Index Fund (Nasdaq: YDIV) (the "Fund"), has approved changes
to the Fund's investment objective. On or around August 29, 2018, the Fund will
seek investment results that correspond generally to the price and yield (before
the Fund's fees and expenses) of an index called the S&P International Dividend
Aristocrats Index (the "New Index") and normally will invest at least 90% of its
net assets (including investment borrowings) in securities comprising the New
Index. The New Index will be developed, maintained and sponsored by S&P Opco,
LLC ("S&P").

The Board of the Trust also approved a reduction in the annual management fee
payable by the Fund to First Trust Advisors L.P. ("FTA"), the Fund's investment
adviser, from 0.70% of the Fund's average daily net assets to 0.60% of the
Fund's average daily net assets. FTA will manage the investment of the Fund's
assets and will be responsible for the Fund's expenses, including the cost of
transfer agency, custody, fund administration, licensing fees, legal, audit and
other services, but excluding fee payments under the Investment Management
Agreement, interest, taxes, brokerage commissions and other expenses connected
with the execution of portfolio transactions, distribution and service fees
related to a Rule 12b-1 plan, if any, acquired fund fees and expenses, and
extraordinary expenses, which are paid by the Fund. The reduction in the
management fee will have no effect on the services provided to the Fund by FTA
and will be effective on or around August 29, 2018. It is also anticipated that
on or around August 29, 2018, the Fund will change its name to First Trust S&P
International Dividend Aristocrats ETF. The Fund will continue to list and trade
its shares on Nasdaq under the ticker symbol YDIV until August 29, 2018, at
which time the Fund will list and trade its shares on the Nasdaq Stock Market
LLC under the ticker symbol "FID." The Fund will obtain a new CUSIP and other
identifiers.

The New Index is designed to provide broad international (excluding the United
States) equity exposure to the 80 securities in the S&P Global Broad Market
Index that exhibit high levels of income by growing or maintaining a consistent
dividend over a long time horizon.

FTA has served as the Fund's investment manager since the Fund's inception. FTA,
along with its affiliate, First Trust Portfolios L.P., are privately-held
companies which provide a variety of investment services, including asset
management and financial advisory services, with collective assets under
management or supervision of approximately $126 billion as of May 31, 2018
through unit investment trusts, exchange-traded funds, closed-end funds, mutual
funds and separate managed accounts.
